## The Big Ones

The following is a summary of the main features added to darktable
4.6. Please see the user manual for more details of the individual
changes (where available).

- Editing history is now periodically auto-saved (every 10 seconds)
while editing images in the darkroom view. The auto-save interval can
be changed (via a preference) or auto-save can be disabled entirely
(by setting the interval to 0).

- A new processing module _rgb primaries_ has been added. This module
can be used
for delicate color corrections as well as creative color grading.
It allows the red, green and blue primary colors to be moved around
using "hue" and "purity" controls.

The underlying pixel operation is essentially the same as channel
mixing.

- In addition, the _sigmoid_ module now includes a new _primaries_
section,
which can be used to gracefully handle difficult lighting situations
(e.g. LEDs) and tune the overall look of the image. Modifying these
parameters can provide pleasing sunsets, improved skin tones etc.
This feature can only be used with sigmoid's per-channel mode and is
loosely based on ideas from Troy Sobotka's
[AgX](https://github.com/sobotka/AgX-S2O3)
and related work in the [Blender
community](https://blenderartists.org/t/feedback-development-filmic-baby-step-to-a-v2/1361663
).
The included "smooth" preset should provide a good starting point
for further corrections using this feature.

- When working with the liquify and retouch modules, the full uncropped
image is now always shown, with any crop indicated by displaying an
overlaid
rectangle. This allows for cropped-out parts of the image to be used
without
having to first disable the crop module and re-enable it when
finished.

- When panning or zooming in the darkroom view, a low resolution
placeholder
used to be shown until the image was fully recalculated for the
newly-visible
region. Now, if any part of the previous view is still visible, that
part will
be immediately shown in high quality, with only the remainder of the
image
being temporarily shown in low quality until the pipe has finished.

This has been achieved as part of a complete reworking of the
darkroom image
display, which has also removed some annoying jumps when
replacing the low resolution placeholde

Hello!

I'd like to take some time, while we are all waiting for the 4.2
release, to send you a little message about darktable.

This release cycle has seen lot of improvements as previous releases.
We had also some divergences with one developer and the signal sent was
certainly not good or worrisome for some of you.

Fact is that the team behind darktable is strong and working very hard
in many aspects of the project.

Some people gain more visibility because they work on GUI part that are
directly visible by end-users. But there is also some people working on
part of the code that you do not see directly but that makes darktable
internal better.

I'd like to thank Hanno Schwalm and Ralf Brown for their work on
performances, tweaking OpenCL code path and OpenMP to use every cycles
of your CPU.

I'd like to thank Hanno Schwalm also for working on new highlight
recovery algorithms.

I'd like to thank Diederik ter Rahe for looking into Gtk issues and
proposing a very impressive framework for shortcuts. And to achieve
that, lot of code refactoring has been done. Some Gtk parts are looking
like black magic to me :)

I'd like to thank Roman Lebedev for the hard work in rawspeed. Without
this project darktable won't be there. Also Miloš Komarčević working on
rawspeed and many RAW formats support.

I'd like to thank Victor Forsiuk for working on image input/output
support and fixing a huge number of spelling typos.

I'd like to thank Aldric Renaudin for the continued effort on the
lighttable filters and UI.

I'd like to thank Nicolas Auffray for taking over the UI effort and
doing magic with CSS.

I'd like to thank Bill Fergusson for maintaining the Lua framework.

I'd like to thank rawfiner for checking noise profiles and making sure
they are in good shape for integration.

I'd like to thank Simone Gotti for working on a new lens correction
method based on meta-data.

I'd like to thank all the testers and reviewers (Chris Elston, Martin
Straeten, parafin, Mark-64, and others) making sure we do not introduce
more issues than we are fixing. Also thanks for Chris for reading my
English in the RELEASE_NOTES and correcting it.

I'd like to thank parafin and Bill Fergusson for creating the release
binaries for MacOS and Windows. And Andreas Schneider as maintainer of
the OBS platform for creating the GNU/Linux binaries.

I'd like to thank Sakari Kapanen for helping with color science.

I'd like to thank Jakob Andrén for the long journey at making Sigmoid a
viable alternative to FilmicRGB.
  
I'd like to thank all the translators bringing to us an interface in

our native language.

I won't name them, but also remember that darktable is Open Source and
we leverage on many other Open Source projects/libraries (to handle
Jpeg, TIFF, AVIF, HEIF, PNG... tether with camera, handle SVG,
colors...). I'm even pretty sure that there is far more code in the
dependencies we are using than in darktable itself.

And finally I'd like to thank all people that I have forgotten in the
list above. I'm sorry if I missed you.

A darktable release is a huge amount of work and the darktable team is
wonderful. I'm really happy to be part of it, let's the aventure
continue.

Have all a nice end of year!

Agree with Patrick.

It is more likely the DD responds with corrupting the data because of

If it is a spin disk – you may want to check it for bad sectors. But

This is the second time this happens since running dt 4.0 : pasting

After over one hour waiting in vain, I have to kill dt. Then, the

switch the computer off.

When I restart it, te DD is no more mountable, nor accessible by Gparted.
The only way to read it is memtest, which sees the partition and the

It takes about two hours before the scan is finished, so I can copy

I hope it will end soon, so I can check all ran fine, but this is how

Re: [darktable-user] Collections module

2022-08-12 Thread I. Ivanov


Hi Bruce,

You may want to hover over the tag. There are a few switches.

You can try %tag with the % being the wild card or if you have hierarchy 
you can click or ctrl+ click etc.


Also, you may want to make sure there is no some limitation introduced 
by the collection filters

Have I done something to cause this?
Can I get back the ability to search tags and have child tags included

Re: [darktable-user] Darktable-exported EXIF ignored by flickr for Samsung NX

2022-07-07 Thread I. Ivanov

I had a few pictures in Flickr without EXIF, and then I realized that DT 
did not include it. This is because each export style has its own EXIF 
export setting. So some of my styles did have EXIF in them and others 
did not (so it was my fault).


I normally check the data with Geeqie. The only remaining thing is to 
confirm with another app if EXIF is there or not. If it is – then maybe 
Flickr is doing something odd.


To my knowledge – if DT is exporting both – it shouldn't care if the 
image originates in Pentax or Samsung.

B

Dear darktable users
This is mostly flickr question, I know. Apologies for that, but it's
also darktable related, since the issue occurs with darktable-exported 
jpgs.


In short: Flickr is ignoring the exif data for Samsung-NX pictures,
while it works fine for Pentax K-*.

Working example Pentax K-3 II: https://flic.kr/p/2niiAah
Non-working Samsung NX3000: https://flic.kr/p/2nvyzYU

Both pictures have been exported with exactly the same settings in the
export module. Actually, if I view the jpg in gthumb, also the NX
picture *does* have all exif -- that's why it's probably not a darktable
issue, but a flickr issue. Nevertheless, I'm happy for any replies or
suggestions.

Thanks in advance, best regards,
Michael

Re: [darktable-user] Use of the geotagging module

2022-03-13 Thread I. Ivanov

Replying back to the list (instead of personal email)

I did the tagging only once in the past but I was able to tag about 
9000+ images.

My notes are not that clear...

Looks like

1. I changed the time of all images to UTC (but this is the actual time 
- not the zone)

2. When changing the offset - I select several images and then try to 
modify the first (change the time by directly typing the desired time 
stamp) - this applies offset on all images - it does not change all 
images to be the exact same time.

3. What is unclear is - when I am importing the track and the images are 
already in UTC - is the zone your local zone or the UTC zone - I have 
the feeling that I changed the "time" to UTC but and I changed the zone 
to PST (my zone) - you will have to experiment with this.

4. Once the images have the coordinates from the track I changed back 
the time to the original one and they preserved the coordinates properly.

Hope it works for you. It would be nice to have a newer video but 
honestly I never had time to do that.

[darktable-user] tone equalizer alternate wheel behavior

2022-02-20 Thread I. Ivanov


Hi,

In tone equalizer normally the wheel of the mouse controls the exposure 
compensation.


Every now and then the behavior for me changes - the wheel controls the 
zoom of the image. Restart of DT fixes the behavior to the default one.


Question - is there a shortcut that alternates exposure controls in tone 
equalizer vs zoom of the image? I maybe activating it unknowingly. On 
the other side - I would like to be able to activate zoom instead of 
exposure when I want to. So if such shortcut exists I would really want 
to know it.


I have very few shortcuts defined myself

Re: [darktable-user] Re: split of Crop and Rotate to "Crop", and, "Rotate and Perspective" in 3.8

2021-12-31 Thread I. Ivanov

I am in the same boat - I use crop and rotate together all the time. 
However - I do see the reasoning for separating them and it was a bit 
going back and forth before when I had to apply both perspective and crop.


One suggestion however (not sure if it is possible).

Is it doable at all - that the crop in "Rotate and Perspective" be 
exposed as an alias in the crop module? So when rotate is initiated in 
the crop module - it actually activates the "Rotate and Perspective" and 
adjusts it there?


If that would work - maybe it would be the best of both - separate 
modules but an alias that does not work on its own - just controls 
something else.

Hi,

It does remember what was last used except that when I had dropped the 
opacity for a single use it seems to set that as a new starting point. 
So when I have restored my need for 100% opacity and finished on 100%, 
my next use will stat at 30% and then I have to scroll up to 100%.



Hi Andrew,

For me it appears to stick to whatever I set it.

- If I start retouching (at any opacity - say 90) and after that I 
change the opacity of the existing shape to 100 - the next retouch will 
use the 90 as a starting point (because this is what I started with) but


- If I first set the opacity (say 100) then each shape I make will be at 
the chosen opacity. This also appears to persist between images, between 
restart of DT and also between different tools - the opacity set in 
retouch will persist in other modules (for example haze removal). Vice 
versa is also true - opacity set in another module will carry forward to 
retouch.


I am not sure if there is some specifics to os / version etc. but just 
FYI - I am on pop OS 20.04, DT 3.6.1


It is good that the suggestion from Patrick helps you. But unless there 
is something apparent like version, OS etc - I don't know why would it 
behave different.


Sometimes I try backing up (renaming) ~/.config/darktable in order to 
start afresh (for a test) but what it would tell me is if there is 
something that exists in the config files that triggers the behavior or 
not. But this would be mainly to satisfy the curiosity.

True, not this one. But there were plenty of others, for example when

tries to apply changes to the image before it is completely loaded.

I am also using crop and rotate (but I  have seen it in the new crop

Even now (the image is fully extended) and can't capture with the

For the test - I deleted the complete history and tried (this time with

As I said - it is not consistent. Sometimes it works and sometimes it

As soon as I changed from perspective to rule of third it worked.

Re: [darktable-user] Add to library, select only new pictures question

2021-07-25 Thread I. Ivanov






It's not entirely clear to me when I select select only new pictures 
while importing pictures, how does darktable determines the new 
pictures? Is it new pictures for the destination folder/collection or 
does it look at complete database and see if the filename is duplicated.


I don't think it looks in the complete DB. One and the same image can be 
imported more than once on different locations (has been like this for 
long time). An image gets an ID (light table - image information panel)


Most likely just compares the images in the folder.

After you move the images to another location - right click on the film

do the rest.

router) DT does good work with the caching. It does fetch the raw file 
but after that works out from the cache quite a bit (just an idea).

Re: [darktable-user] darktable Backup instructions / guide?

2021-07-05 Thread I. Ivanov

All the information on file level is preserved in .xmp - if you keep the 
.xmp you can restore the processing.


If you want something more - I'd keep the complete darktable folder. On 
Linux it is .config/darktable likely similar on windows but under home 
folder programs and features or something like this.

You are strongly advised to take a backup first.

- Almost 2680 commits to darktable+rawspeed since 3.4
- 954 pull requests handled
- 290 issues closed

## The Big Ones

- Full rework of the import module. The new module allows you to see
thumbnails of your images before import and makes it easier to handle
multiple import tasks. The same dialog is now used for importing
from disk, card or camera.

When importing "in-place", images that are already present in
darktable
are flagged and can be automatically excluded from the import.

Importing from a local drive won't use gphoto and so should work more
reliably on Windows.

- A vector-scope is added to complement the current histogram,
waveform and parade views.

- A new default demosaic algorithm (RCD) has been introduced, which
should provide
better quality than the current default (PPG) without the long run-
times
of AMaZE. the order of the demosaic algorithms has also been adjusted
for clarity.

- Support for "dual demosaic" has also been added, allowing you to
combine
"RCD + VNG4" and "AMaZE + VNG4" for bayer sensors, for xtrans sensors
there is
"Markesteijn 3-pass + VNG". This allows you to use an algorithm
better resolving
fine detail and another one delivering smoother output depending on
local image content.

- You can now create an opacity mask based on the sharpness of the
image. This uses
a similar algorithm to that used in dual demosaic.

- Drawn shapes are drawn on the original RAW image and then distorted
through
the pixelpipe. This previously led to, for example, circles becoming
ellipses
(due to lens distortion) after being placed on the image. All drawn
shapes can
now be pre-visualized and moved prior to placement, with full
deformation
applied. This makes the editing of masks easier fully WYSIWYG.

- A new Color Balance RGB module has been added. This can be used as a
one stop module
for all color grading work.

- A new censorize module has been added. This allows you to hide parts
of the image by adding
a blur/pixelization.

- A new crop module has been added. This new module has been added late
in the
pixelpipe and makes it possible to use cropped parts of the image for
source spots
in the retouch module, for example.

- A new section has been added to the color calibration module to allow
you to calibrate
colors using a color checker chart.

- The map module has been enhanced in a number of ways:
- When importing a GPX the trace can be displayed.
- Location can be set using polygons and directly created from
information
reported by Open Street Map. As a reminder, all locations
create tags automatically for images placed into the area.

- The basic adjustments module has been replaced with the quick access
panel, which
can be used to group controls from multiple different modules in one
place. Currently,
only non-graphical controls (sliders, comboboxes etc.) can be used.

## Other New Features And Changes

- The various lighttable modes can now be accessed via clear and
descriptive icons
at the bottom of the screen. These should be easier to use than the
existing drop-down
selection.

- The export module is now also accessible on the left-hand panel of
the
darkroom view.

- The mix control in the contrast equalizer module is now retained as
module parameter. This means that no data is lost when using this
slider and
you can always change the mix later with full precision.

- The following modules have been deprecated:

Re: [darktable-user] Will the next release of darktable support CR3 files?

Not everybody can code. This does not mean they don't contribute in some

Nothing to do with demand - it is just acknowledging the reality.

I am using popos Patrick - it is ubuntu based.


if opensuse system, no need to bother with *buntu* packages, keys, or
anything else.  openSUSE provides all the packages necessary for building

[darktable-user] image selection lighttable 3.2.1

2020-08-12 Thread I. Ivanov


Hi All,

I noticed a change how image selection works in lighttable 3.2.1 
compared to 3.0.2


When viewing in full screen (press and hold "w") and advance - I was 
able to click enter and mark the image - then when I release "w" the 
image on what I hit enter remained selected so I can easily go to it.


In 3.2 the image on what i press enter is highlighted but as soon as I 
move the mouse to go to it the selection disappears.


Does anybody know if this is intentional?

You should distinguish the two "problems":


yes sorry

a) power supply disconnects (this is critical as when it happens it 
drains the battery).


b) too hot - I am starting to see a pattern that this is a general ryzen 
3900 issue




- the CPU gets too hot: maybe it is not a problem, it is what it is. 
Notebook's thermal limits are always compromised, even on "gaming 
machines". You can clean filters, fans, re-apply thermal paste, but in 
the end the limits are still there.


- the BIOS and/or kernel is not throttling the CPU as it should, and 
this is causing the hardware safety switches to shut down the 
computer. Some safety measures are not reset until you fully cut the 
power to the motherboard, so it's not strange that you need to 
disconnect the power brick to turn it on again.


What are the peak temperatures of your computers when under load?


Mine (Intel 4720HQ) goes up to 97-98°C before aggressively throttling 
back. You should check on AMD's site which are the warning and maximum 
temperatures for your particular CPU, and compare them with the data 
the system has. For example, using the command "sensors" for me shows:


Package id 0:  +55.0°C  (high = +84.0°C, crit = +100.0°C)


Thank you!

On completely idle machine I am getting

iwlwifi_1-virtual-0
Adapter: Virtual device
temp1:    +40.0°C

BAT0-acpi-0
Adapter: ACPI interface
in0:  12.35 V
curr1: 0.00 A

k10temp-pci-00c3
Adapter: PCI adapter
Tdie: +71.9°C  (high = +70.0°C)
Tctl: +71.9°C

acpitz-acpi-0
Adapter: ACPI interface
temp1:    +73.0°C  (crit = +120.0°C)

When hot - it goes over 100 C - about 104 to 107.



which is consistent with the thermal throttling in my CPU when the 
temperature is around 85-95°C. As I said before, unless the throttling 
safeguards are improperly configured or disabled, your CPU should 
never get hot enough to shut down under normal operation. My CPU is 
old and power inefficient by today's standards, and even then it's 
capable of working on passive cooling alone by automatically lowering 
the frequency to the minimum (accidentally tested once the fans got 
stuck).


Things to check:
- is frequency scaling working at all?
- which is the frequency scaling governor?
Some info: https://wiki.archlinux.org/index.php/CPU_frequency_scaling


Thank you - will check that.

That sounds more plausible than the power brick knowing about the

Yes - it came with it. To make it worse - the manufacturer replaced it 
and the second machine (new machine, new power brick showed the same issue)


https://www.rapidtables.com/calc/electric/Amp_to_Watt_Calculator.html

11.8 Amps at 19.5 Volts calculates to 230.1 Watts. The power supply is 
230 Watts. Unless the .1 Watts is significant or there is an error of 
some kind then they are extremely close.




A recent computer with a recent kernel should never get to the point 
where the CPU turns off because of high temperature, it should 
throttle much earlier. If that is not the case, you may check if 
automatic throttling is not disabled somewhere.

It is really odd. It is a brand new laptop and I can reproduce the issue

I am really puzzled how the power supply knows or reacts. It is just a

Hi All,

I know it is quite a stretch but  have anybody heard of a

its own?

I am observing a very strange issue on a linux laptop and I can only
simulate it for now when DT is used - using GPU - new AMD processor,
exporting thousands of images then - when the temperature rises -
start
intense disk operations (copying of files for example). Unplug the
power
adapter from the wall is needed to restore the power.

If anybody is using AMD based linux laptop - would you mind please
sending a screenshot from "Psensor" when the computer is heavily
utilized (like exporting thousands of images out of DT using GPU)? I
would really want to know the temperature scope.

The ones of main concern for me are "Tdie" "Tctl" "temp1" (the 4th
value
top to bottom on Psensor)

Have anybody seen more than 100 Celsius on the above values on any
laptop when under stress? If not - what do you observe as a normal
scope
for you when the machine is under stress?

[darktable-user] power adapter disconnects - high temperature

2020-08-09 Thread I. Ivanov


Hi All,

I know it is quite a stretch but  have anybody heard of a 
possibility of a power adapter cutting the power to the laptop on its own?


I am observing a very strange issue on a linux laptop and I can only 
simulate it for now when DT is used - using GPU - new AMD processor, 
exporting thousands of images then - when the temperature rises - start 
intense disk operations (copying of files for example). Unplug the power 
adapter from the wall is needed to restore the power.


If anybody is using AMD based linux laptop - would you mind please 
sending a screenshot from "Psensor" when the computer is heavily 
utilized (like exporting thousands of images out of DT using GPU)? I 
would really want to know the temperature scope.


The ones of main concern for me are "Tdie" "Tctl" "temp1" (the 4th value 
top to bottom on Psensor)


Have anybody seen more than 100 Celsius on the above values on any 
laptop when under stress? If not - what do you observe as a normal scope 
for you when the machine is under stress?


Thank you in advance!

Re: [darktable-user] DT & life on the road

2020-08-04 Thread I. Ivanov





I don't want to have to do the work twice. What do you suggest to pass
the DT work done on the laptop to the desktop at home?

As long as you have the .xmp created - when you import it on the home 
computer - it would be fine.

There are few scenarios that are a bit unclear

- the large USB - are you going to copy the images or use it from the 
USB? Either way - you can simply import on the second computer and it 
will read from the .xmp


- once you move the images on the home computer - what happens with the 
laptop? - if you want to avoid confusion and both computers are 
accessing the same USB - then you will have to consider synchronization 
of the library (or easier - delete the library on the travel laptop).


FYI - recently I was experimenting on a laptop with removing / 
recreating / replacing of "library.db" - it was as easy as stop DT then 
either rename or delete library.db - DT was very robust and just worked. 
The only "odd" item that happen when I was experimenting was having old 
cache with new images - it simply would display the old images in light 
table then when modify it in darkroom - it will update the preview. Of 
course - easy to remove the cache altogether and then run 
darktable-generate-cache.


What you want to avoid is using 2 different libraries (that are not 
synchronized) and accessing the same images and editing them (because 
the 2 instances can override one another) but reading the request I 
don't think this is going to happen.


You can also utilize check for .xmp changes on startup - it works but 
the drawback is for a big library (many thousands of images) it may take 
a while. So you don't want to have this setting all the time.


Hope this helps,

Re: [darktable-user] Camera calibration profiles

That sounds quite complicated. I just want to be able to use the

If you "really" want to reproduce what the camera JPG produces - you can 
try the following


- the camera manufacturer includes a program to manipulate the images
- this program includes .ICC profiles - for example - Canon includes 
PS.ICC for (Portrait SRGB), PA.ICC (for Portrait Adobe RGB) and so on.

- take these profiles and place them in /$HOME/.config/darktable/color/in
- then use them as "input color profile" from within the input color

- most likely you will want to activate "unbreak input profile module" 
and also adjust the sliders in it and brightens / contrast saturation

Now the more important questions - do I recommend it, do I use it?

No. I don't use it.

In my opinion - DT has way better tools and as the others suggested you 
can achieve much better results than the .jpg


In my opinion - for beginner this is a good resource

https://www.youtube.com/user/audio2u
Bruce is very detailed in explaining the various modules.

I started with the tutorials from Robert Hutton
https://www.youtube.com/user/rhutton86
and even they are older I still find a lot of value in them.

If you really want to go in deep details why things are constructed the 
way they are
Check the videos of Aurélien PIERRE. A note of caution however. These 
can require patience to comprehend because they are from developer's 
point of view.

Re: [darktable-user] Windows or Linux?

2020-07-18 Thread I. Ivanov





Which platform (Windows or Linux) will give darktable work better on?



Linux!!!

I am using a 9 year old Dell XPS i7 gen 2 (sandy bridge) (8 cores total) 
- 8GB RAM and PopOS 20.04 that I upgraded to few weeks ago. And I prefer 
to use this machine compared to Dell Precision - Windows 10 Professional 
with 16 GB Ram - 8 cores i5 or i7 (not sure) - Gen 8  - 1.5 year old 
again 8 cores.


I didn't buy the Windows - I have it from work and work on it daily (I 
don't use it for personal use except to try one program or another). The 
windows has even GPU Nvidia Quadro P1000 that Darktable utilizes but I 
see no significant improvement in performance.


With all that windows has to offer on the hardware (I mean the Dell 
machine) I feel that the performance and experience did not match Linux.


Because of my older configuration - I used Ubuntu 16.04 with Darktable 
2.6.3 and this configuration (on the 9 year old machine) would happily 
compete with Windows 10 Professional (the new 1.5 year old computer) 
with Darktable 3.0.2


Now since my 9 year old machine is upgraded to Pop OS 20.04 - Darktable 
3.0.2 still works great but in some modules (like denoise, retouch) I 
can feel the aging hardware. Even with this - the service that I 
received from the hardware (Dell XPS x2), Linux and Darktable are more 
than impressive.


I don't know what the experience is to run Darktable on a brand new 
machine under Linux. Looking at youtube videos sometimes - majority of 
the presenters that run Linux appear to have better experience than my 
Windows 10 professional. By the way - they are not only running 
Darktable - at the same time they record the video for youtube.


Hope you will find the best platform that serves your needs. I made my 
choice and it is Linux.

B

Re: [darktable-user] removing broken storage and zoomable lighttable

2020-01-04 Thread I. Ivanov


Not sure if comments are supposed to be here or on github.

I use google photos but "never" directly from DT. I consider it over 
complicated because when something breaks - it is difficult to 
troubleshoot. So if it would save time and effort for development - I 
agree dropping the exports to google / flickr etc. is better. There are 
better areas to invest development.


Zoomable LT - I tried to use it but ended permanently with file manager

I am in the same shoes. Using GeForce GT 525M/PCIe/SSE2 and it is slower

if the GPU is significantly faster because there is time lost when the

Check man darktable

If you start from command line like this

darktable --library :memory:

it won't read the library so you can try opening the same image and 
exporting to see if it will make any difference.

To me, it looks like Jpeg compression artifact. It's a high-res 
photo, yet only about 200 kB. Have you tried exporting into png or 
tiff to see what the image actually looks like before compression? If 
you are no artifacts in lossless files, try exporting at a higher 
Jpeg quality setting, and, if you really need small files, use a 
lower resolution instead of increasing compression (lowering quality).

Re: Fwd: [darktable-user] copy masks

2019-10-04 Thread I. Ivanov


I think they don't work in a uniform way.

For example - if you create a mask in the color correction module 
(simple circle) then go to light table and copy / paste the module - it 
will inherit the mask in the new image.


On the other hand - if you are still in darkroom and try the same using 
the film strip on the bottom - it did not work for me.


I am using ubuntu 16.04 / DT 2.6.2

You may be able to experiment with copying the side cart to a new name 
(like a template) and then try to load it (I haven't tried it myself).

But I'm wondering if you would be able in any way to copy the parts of

Clearly, this is not an ideal solution (if it works at all), but it

Dear darktable community,


I have been using DT extensively over the last two years. Now I come to
the point that I dare to ask some questions which I could not figure out
my self.

In order to process bracketing images from a tripod I would love to copy
masks from one image to another. When simply copy and pase the module
stack to the new image, the drawn masks are gone. I guess that is
intentional for most images, however, in some circumstances it would be
useful to apply them as well.

Any ideas how I could achieve that?

[darktable-user] core options memory settings

2019-09-03 Thread I. Ivanov


Hi All,

I am trying to optimize the core options for my system. It is an 8 year 
old laptop with 8Gig RAM and 500 GB SSD.


GeForce GT 525M/PCIe/SSE2 (apparently too slow).

Intel® Core™ i7-2630QM CPU @ 2.00GHz × 8 (sandy bridge 4 cores 8 threads 
if I am not mistaken).


Ubuntu 16.04 / DT 2.6.2

I read https://darktable.gitlab.io/doc/en/core_options.html

The memory settings are displayed in minimalistic approach

My (current) settings are

1. thumbnail cache 3096 (I tried with lower values but looks like it 
impacts lighttable more than I would like to) - I do have the back end 
disk cache enabled.
2. number of background threads 16 (I used 8 for a long time but didn't 
observe ill effect for now by increasing the value)

3. host memory limit for tiling 2500
4. minimum amount of memory for single buffer tiling 48 (I kept this to 
16 for a long time but it looks like increasing the limit is beneficial 
- not sure if I am doing the right thing here).


What do you use (or what would you use if you were in my situation)? 
Again - this is an older machine and I know that it is having a 
challenge. I am simply trying to set it to the best I could. When I use 
DT normally I turn off all other programs except system monitor so I can 
keep an eye on the memory usage.


Thank you in advance...

Re: [darktable-user] OpenCL error starting dt

2019-08-16 Thread I. Ivanov


Hi Jack,

Can I ask for clarification please? openCL on Intel CPU is black listed 
*regardless of the GPU* (Nvidia / Radeon) or this affects only the build 
in Intel GPU (that is integrated on the processor)?


Thank you,

Re: [darktable-user] Looking for some use cases for a metadata editor in darktable

2019-08-07 Thread I. Ivanov





have you looked in an xmp file for the date?


I may be missing something here but what I did - I imported few images 
then applied time offset +9h in my case. This did change the image 
information pane to show the correct time since I offset it. However - 
when I exported the images with copy - creating the name based on the 
EXIF - it does place correct time within the file name as I offset it 
but the new image has still the original time - before the offset was 
applied. I checked after that the XMP and I cannot locate entry about 
time modification / offset etc. So... either I don't know what to look 
for or the entry is simply not there. To me this is a metadata editing...


What I tried - I offset the time - xmp is produced. Time is correct. 
Removed the images then re imported them (the xmp is present no change 
to it). Time offset is gone. Looks like this is likely preserved only on 
DB level.




iianm, an "undo" function currently exists.

How do you trigger it in lightroom? Is it in DT 2.6.2? I can see very 
old FR https://redmine.darktable.org/issues/8498 and it is still open. 
Also this one 
https://darktable.gitlab.io/doc/en/metadata_editor.html#metadata_editor 
and this one https://darktable.gitlab.io/doc/en/tagging.html are not 
saying anything about undo / redo.

Hi,

I'm looking at adding a full metadata interface to darktable, I've 
already posted to the developer mailing list

made a pull request on github 
 about this but 
I'm looking for some input from users. So if you would use this, what 
sorts of metadata fields would you want to edit? How many photos would 
you edit at a time? And how would you select these (manually or via 
collections)? Do you have any other suggestions?


I usually use description, tags, creator, rights. Description tends to 
get longer for me... I tend to name the pictures after the date. 
(MMDD-MMSS). Some times I am struggling with pulling this from EXIF 
- specifically when I have to offset the date +- 1h or more because of 
incorrect clock. Not sure if it is possible but if I change the date I 
would like it to carry forward. I understand modifying RAW is not a good 
idea and agree with it. But if the info is recorded in the XMP and the 
user can elect to read the XMP it would be nice.


I miss having keyboard navigation in the tag area - for example left 
arrow to collapse branch, right to expand...


I regularly tag and include metadata for 500 - 900 images at a time. 
Currently working on 10k so I may end up with 2000 or more keepers (that 
will have to be tagged)


Currently - I don't think there is an easy way to copy / paste all 
metadata or few fields from one image to another (or many others). If 
the fields increase - it would be nice to have such.


I've had cases when by mistake I overwritten tags / metadata on 
considerable number of images. Having undo / redo feature would be very 
good actually very very very good.


Not sure if I am understanding correctly but new interface - do you mean 
a completely separate are from lightable? Or still part of lightable? 
There are other items that can be considered - like better visual 
identification what is being tagged / edited but this can also crowd too 
much lighttable...

Re: [darktable-user] import process / workflow

2019-07-20 Thread I. Ivanov





smb is slow and you have quite a large collection being imported.  I would
*guess* that dt has not had time to generate the previews yet.

perhaps a better plan would have been to download the images to the smb
drive or via nfs/sshfs first and then to import to dt.  but that would
probably still have been much slower than a local drive.


I had considerable issues with DT files stored on USB connected to a 
router (make believe server) and shared using SMB (took forever to 
import and work).


Oddly enough - if I am to copy the images back and forth using Nautilus 
or command line - it would work much faster.


Few months ago I changed the firmware to an open source one and gained 
access to NFS shares on the router. Since then - the speed have 
increased significantly. I mean specifically when DT r/w from the router.


Few days ago I copied more than 10k directly to the USB (connected to 
the router and shared over NFS). I am currently working out of it 
directly - on a 8 year old laptop and the speed is okay. I mean - the 
bottle neck is not any more the router. If you are on synology - you 
*should* be able to have NFS share. For me - the experience with DT 
reading images over NFS is much better comparing to the one over SMB. 
You may be able  to improve r/w performance on SMB with forcing 
different mounting options like smb version but none of it was very 
reliable for me.

I would be surprised if you'd get this working at all. The (IMHO) most 
important aspect of h.a. photography is the shear distance between you 
and the subject.That can add up to 50 kilometers or more (as you can 
clearly see from your mountain pictures).
Between you and the subject there are so many moist and dust particles 
that half of the light is gone, and the other half is distorted. And 
you don't even get to chose which half you get.


I live in remote flat area with outlook on distant mountains. And I 
see the same sort of problem. On a sunny, dry summer day "my" 
mountains are grayish and dull , while after a big storm I have clear 
vision, with vivid colors for at least 25 kilometers.


My best guess is that successful h.a. photographers simply wait for 
the best opportunity: such as after a big rain, when the air has been 
washed clean. Or during winter time, when the air is dry(er).

[darktable-user] high altitude photography correction challenge

2019-07-17 Thread I. Ivanov


Hi All,

Recently I took some pictures on a higher altitude - Untersbergbahn 
GmbH. What I noticed is that they have quite a strong blue hue to them. 
This however is only for the landscape pictures (mountains / valleys) 
that I took. The pictures I took of people (few meters away) are just 
fine. I did take gray card white balance and  the one facing the sun 
measures at temperature 6498 while the other (slightly tilted to be 
shaded) measures at 8984. I was unable to produce a pleasing result with 
either - even with standard cloud / daylight settings in DT.


I used Canon 70D with 50mm 1.4 lens with polarizing filter. However - I 
did not see much difference to the pictures taken on 18-135mm lens.


DT is 2.6.2 on ubuntu 16.04

The link

https://www.dropbox.com/sh/sf7znezb45ghnr2/AADCPgrFycbSPlxaFOfSNWiHa?dl=0

contains two .jpg, CR2 and the 2 .xmp - quite unsuccessful attempt from 
my side to develop the images.


All that I searched on the web points to physical challenges with high 
altitude photography but I was unable to find anything specific when it 
comes to developing such or if I needed special equipment (like specific 
filter) to take such pictures.


Would you be able to have a look please and let me know what I am 
missing? My attempt to develop the picture fails miserably comparing to 
the stunning view from the mountain. The weather was a bit hazy and I 
did not have a haze filter but I can't think of anything else. The 
histograms fitted nicely. Is it simply some particular way to develop 
such images that I am not aware of?


I would appreciate it if you can please point me in the right direction

Thank you,

B

Yes - the challenge is that when this is done I am to press "z" to

Looks like by default - in LT - the prerendering is equivalent to

[darktable-user] pre rendering

2019-05-23 Thread I. Ivanov


Hi All,

I am using DT 2.6.2 on ubuntu 16.04 - older machine.

When I develop one image often I want to carry the changes to another 
10-20 images (in LT).


I can see the changes are propagated properly and the thumbnails 
changed. However - when I press "z" to see the image in full screen - it 
takes some time to render (because my machine is older).


Is there a way to have all changed images rendered at higher res for LT 
as soon as they are changed?


Currently to achieve this I press "z" and try to flip them one by one 
and this seems to trigger the rendering but some times (when I change 
more images) it misses some. This bothers me not only because I have to 
wait but also the blurry image - I have to look away from the screen... 
even if it is for 2-3 sec.


I use disk cache for thumbnails, memory for thumbnails is 2048, and if I 
force disk cache from command line it does create thumbnails at the 
bigger resolution as I want but I am looking for a way to make this work 
automatically while I am normally using the program.

Re: [darktable-user] Export weirdness - odd cropping DT 2.6.1 and DT 2.6.2

2019-04-16 Thread I. Ivanov

I had similar (but not exact) issue before. It happen when I deleted 
images from DT and re imported after moving them to a different location 
(at the time I didn't know that I can simply point the images to the new 
location).


The behavior was - what Light-table presented for some images did not 
match DT. I ended up touching the images (the side carts) then forced DT 
to check for modifications when it starts.


For me - not only the crops were odd but also edits were lost (only in 
Light-table). Since I started simply pointing the folder to the new 
location the images are moved - I have not experienced the issue.

There's also some good discussion about the idea behind the module, and its 
approach to colors at the luminosity extremes here:

  https://discuss.pixls.us/t/filmic-a-personal-view/9990/61

If your goal is to retain extreme golden-hour yelowish casts, you might need to 
work somewhat outside of what the author intended the module for. That doesn't 
mean you can't still use it, but you'll probably have to counterract some of 
what it tries to do by default. Once you develop a good default preset to 
replace the basecurve with, it does offer a nice set of parametric controls for 
further adjustment when you want it. Again, this is probably not exactly how 
the author intended it to be used, so keep that in mind as you find your own 
optimal workflow. :)

Thank you! I was not aware of this last discussion. Will certainly read

The filmic module doesn't try to match the base curve, at all. If you want to
do that you'll have to manually set it to some fairly extreme settings. Even
doing this, the colors will be different, partly because basecurve is before
the input color profile in the pipeline, and tends to push colors to extremes,
and partly because filmic is, in part, specifically built to avoid these
unnatural saturation extremes. Hence even with similar curves, you might need
to use additional color tools if you want to emulate what basecurve does (and
in that case, you might want to just stick with basecurve).

Anyway, attached is a quick and dirty attempt to at least get the filmic curve
into the same ballpark as the basecurve, as a place to *start* with a
comparison, at least. :)

Thank you, this is a very good example! I guess I have some learning

@Remco - I just tried 15EV preset and extreme luminance about 50% -

Besides - this is just a sample. I am observing the same in images that

module), and with the 15EV preset in "filmic" increase the 'extreme luminance
saturation' to about 50%. You will still get differences wrt the standard
basecurve.

It looks like the reds are over-exposed (clipped in the raw data), so hard to
get something realistic out of it as you are missing data.

[darktable-user] filmic vs base curve

2019-04-08 Thread I. Ivanov


Hi Guys,

I have tried to use the filmic module.

I am very confused at the coloring filmic is giving me - much redder 
images and reduces the yellow tones.


https://www.dropbox.com/s/p7kvfgm7vggzey1/20150323_060922_9296.CR2?dl=0

https://www.dropbox.com/s/8enxw2mptakh9bb/20150323_060922_9296_01.CR2.xmp?dl=0

https://www.dropbox.com/s/c9muec00sjeyw2k/20150323_060922_9296.CR2.xmp?dl=0

It is possible to change the image of course with color correction or 
something else. But when I compare filmic vs basecurve - the basecurve 
gives me a color very close to the naturally scene while the filmic 
looks much redder to me and it is also loosing the yellow hues seen in 
the golden hour.


I read https://www.darktable.org/2018/12/darktable-26/ and what I am 
perceiving is that it is targeted to balance the image to avoid over 
exposure and preserve details. Color can be enhanced / saturated but my 
concern is the balance. The two results are just too far from one 
another with absolutely minimum processing.


Can you please point me to what am I missing?

Thank you,

B

Re: [darktable-user] Keeping DT in sync between multiple computers

In my workflow I find myself using multiple machines to work on the
same images.  My configuration right now on both machines is to have DT
look for updated xmp files on start up and that seems to work pretty
well.  I usually just ignore the window that pops up to tell me about
newer xmp files, unless the ones that I'm about to work on are listed,
then I select those and let it update the database.

However, there have been some situations where my previous work has
been wiped out when opening a folder on another machine.  Because of
this, I now habitually copy all my xmp files to a subfolder after
working on them in order to keep a back up, just in case.  Occasionally
I need to manually load these sidecar files.

Would an option to disable darktable's database and use just the xmp
files be a feasible option?  How about using something like syncthing
(Linux platform here) to keep the database synced between multiple
machines?  Would doing that cause any foreseeable issues?

How are other people dealing with using multiple machines to work onprojects, 
any tips?

when I use any machine beside my main workstation to edit photos, I issue
darktable as:
   darktable --library :memory:
   import the photos to be edited
   finish the edits
   close dt
and back at my workstation, re-import the edited photos with their
accompanying xmp files.

have not encountered any problems with this work plan.
   


In theory... if you have 2 identical machines (for example linux)
shared network location for DT files
shared network location for the DB, configuration files and cache
same mounting point for the 2 machines

you could use DT on one or the other (one at a time) and the changes 
should be on the 2 machines.


BUT... I haven't tested the scenario please back up if you want to try it.

On the other hand - what Patrick is pointing to is based on experience.

I do this all the time too - works well

Haven't tried this - I usually work the sub-folders one by one.

This will save the new locations on the DB, avoiding any problem

So you can create a temporary collection based on those images which

It is under "select" on the right side of lighttable "select untouched"

Also - collect images - tag - darktable - "changed" - this can be

Re: [darktable-user] shared location multiple computers

2019-01-31 Thread I. Ivanov





It doesn't work over network (on different computers) because DT code
checks for existence of PID:
https://github.com/darktable-org/darktable/blob/master/src/common/database.c
So I guess currently there's no guard against 2 darktables running on
different PCs accessing the same database on network share.

Thank you, I don't know the code... but my understanding is that DT 
"can" run if the database is on a network share and more than one DT can 
connect to it simultaneously.


In my opinion at least 2 possible directions exist

1. Preserve multi client (this can be risky if both clients work on the 
same images) but at the same time opens a lot of possibilities - people 
collaborating together.


2. Enforce single client (this is safer) but at the same time limits the 
expansion.


I think each would appeal to some.

Thank you everybody for sharing thoughts and experience!

    Not sure if I expressed myself correctly... If I backup

    "/home/myhome/.config/darktable" then data.db and library.db would
    be the "correct" ones.
    To my best knowledge - when Darktable works - it uses data from
    the .DB files (not from .XMP) and when the file changes - it
    populates the data to .XMP

    The reason why I am trying to backup the database (as an opposite
    to the .XMP) is because I can easily backup the DB in the cloud
    with multiple versions (and restore what I need). I wouldn't be
    able to easily restore the .XMP files (to the belonging locations)
    even if I manage to accelerate the frequency of their backups.

There's an option on lighttable under history stack "write sidecar

This is very promising! Thank you!

I did few tests and works well. It is exactly the function I was looking 
for.

Not sure if I expressed myself correctly... If I backup

"/home/myhome/.config/darktable" then data.db and library.db would
be the "correct" ones.
To my best knowledge - when Darktable works - it uses data from
the .DB files (not from .XMP) and when the file changes - it
populates the data to .XMP

The reason why I am trying to backup the database (as an opposite
to the .XMP) is because I can easily backup the DB in the cloud
with multiple versions (and restore what I need). I wouldn't be
able to easily restore the .XMP files (to the belonging locations)
even if I manage to accelerate the frequency of their backups.

DT can check for changed .XMP files but I am under impression that
the checking and populating of changes is unidirectional - XMP to

Hi Guys,

I had an unfortunate event to clear metadata from about 600 images (it took

Because there is no "undo" this brings me to the question.

What can I do to have a good backup for such cases? I can backup easily (and

[darktable-user] backup advice needed

2018-12-23 Thread I. Ivanov


Hi Guys,

I had an unfortunate event to clear metadata from about 600 images (it 
took me close to 3h to restore as much as I could).


Because there is no "undo" this brings me to the question.

What can I do to have a good backup for such cases? I can backup easily 
(and very frequent) "/home/myhome/.config/darktable"


However - if metadata (or tags) happen to be deleted by accident and I 
restore the DB - how can I push the DB to re populate the XMP files?

B

[darktable-user] DT speed

2018-12-07 Thread I. Ivanov


Hi Guys,

I am trying to assess and hopefully improve the speed of DT. The 
particular machine that I am testing on is windows 10 with DT 2.4.4. It 
has 2 GPU - built in Intel and Nvidia quadro P1000. The Nvidia GPU is 
4GB RAM, the computer is 16 GB and CPU is Core i5 gen 8.


Currently I can see it is using the proper GPU (Nvidia P1000) but 
utilization wise it is like small spikes to about 40%. RAM - usually I 
don't go above 8GB.


If I put some high values on number of background threads - like 30 - I 
can see it can have 100% of CPU usage for the sake of testing. But this 
is only when thumbnails are being done. I cannot see any speed gain or 
more GPU usage when exporting of pictures. This GPU is 640 CUDA cores 
and I am under the impression that DT is under utilizing it.


Is there a configuration that I am missing or maybe I am 
misunderstanding what to expect?

B

Really no idea. I'm not using Ubuntu but I would think it should has
2.6.0 has the same dependencies has 2.4.x.


Thank you... I hope it would...
