Re: [darktable-user] Feature idea : DTtimelapse ? (similar to LRtimelapse in essence)

with recent darktable there can be a further approach: using exposure and color mapping.These functions might support setting of smooth transitions for exposure as well as color calibration based on keyframesAm 17.04.2024 um 19:08 schrieb William Ferguson :The issue here is that we are trying to solve a darktable problem with a lightroom solution.  If we approach it from a darktable perspective, then we are looking at (probably) less than 100 lines of lua code and 30 minutes worth of work.Using lua I can load an image into darkroom and read or modify the exposure setting.So, if I go through and pick my "key frames", adjust the exposure, then assign a keyframe tag I can run a script that:* selects the images that are keyframes, loads each one sequentially, and reads and stores the exposure information* loads each image in the collection and-- determines the limiting keyframes-- computes the exposure difference -- applies the exposure difference-- loads the next image after the pixelpipe completes.Advantages of this approach* No decoding, extrapolating, interpolating, guessing, etc of XMP files* Don't have to scan for updated XMP files when starting darktable* No worries about XMP file corruption* No worries about database corruption from loading a bad XMP* Don't have to worry about XMP format changes* If the collection gets messed up, you simply select all, discard the history stacks and you've recovered.* You're not limited to just modifying exposureDisadvantages:* It's slower.  It has to load each image into darktable and process it.    I tested loading images and changing the exposure and IIRC darktable  processed roughly 2 images/sec.  The images were on an SSD.BillOn Wed, Apr 17, 2024 at 11:04 AM Jochen Keil <jochen.k...@gmail.com> wrote:Hi Sébastien,I wrote dtlapse back then and I'm happy to see that there's still interest in it. Unfortunately, due to time constraints I cannot put much work into it. Therefore, in its current state it's pretty unusable, since darktable evolves faster than I can keep up.The basic functionality is very close to what you describe. Pick some keyframes, adjust them as desired and interpolate the values in between. This can be done by using the XMP files as interface, once you get around decoding the module parameters. That's all in dtlapse and worked pretty well for its rather hackish state.However, the biggest problem is that modules tend to change regularly, which means that you have to manually adapt the interface description for every new darktable release while keeping old versions for compatibility. I've made it somewhat easy to update XMP interface descriptions by moving them to JSON files separately from the code. Still, for every new release you have to reengineer the XMP file because they're not documented, at least last time I looked. Given the amount of modules (and even if you would limit yourself to the most interesting ones) it's tedious and by the time you're done a new release comes around the corner.I've had the idea to generate the interface description directly from the source code, but you'd need to use a C/C++ parser to get it. I've just checked the code and the XMP interface is STILL hardcoded in the modules.So, to sum it up, it can be done, but it's quite hard. It'd be much easier if the darktable developers would separate the XMP interface definition for each module from the code which would greatly increase interoperability and is good practice anyway (separate data from code). However, I think there's not much incentive for them to do it, it'd even be a rather elaborate redesign.Best,  JochenOn Wed, Apr 17, 2024 at 2:23 PM Sébastien Chaurin <sebastien.chau...@gmail.com> wrote:omg thanks for that !

Re: [darktable-user] darktable 4.4.2 released

[Martin Straeten]

Suspended means, you need do something with the output of these cameras or 
change stuff in the darktable camera support files yourself to enable the 
processing for these images. That might work, but no maintainer cares…
Supporting a camera isn’t just being able to read the files but also to 
interpret them correctly 
darktable just supports cameras, where samples were uploaded so validated 
settings are taken into account. If no user provides those samples, then 
there’s obviously no demand for supporting them…

Re: [darktable-user] darktable 4.4.0 - issue with the macOS package for Apple Silicon (ARM) systems

the official darktable macOS packages aren’t codesigned, so that’s the expected behaviour due to macOS security conceptAm 27.06.2023 um 16:22 schrieb Hevii Guy :
  

  
  
Installation on Mac OS 11.7.6...
Not so sure about the new ARM systems but, for those running
  older Mac OS versions, there is no need to jump through arcane,
  flaming and razor-studded command line hoops. Simply install the
  program by double-clicking the dmg. Acknowledge that you can't
  open it when the troubling dialogue box appears. Immediately
  afterwards, go to System Preferences and select Security
& Privacy. You should then see another dialogue stating
  "darktable.app was blocked yada, yada..". Select "Open
Anyway". Although there might be one more field which you
  might have to authorise, from then on everything will have "stuck"
  and you can start the program as you've been accustomed to.
I would be interested to know whether the above continues to
  apply to Apple's newest OS or if they've created yet another
  "improvement" which makes users' experiences with their product
  miserable.

Hi Martin,
 
no, that's not the problem.
For the macOS ARM64 installation package, you must follow
  the installation notes on https://www.darktable.org/install/
where it says
 
... or you can prevent this from happening by running xattr
  -d com.apple.quarantine ~/Downloads/darktable*.dmg
command before mounting the image (or xattr -dr
  com.apple.quarantine /Applications/darktable.app
after installing).
 
When you do this, the installation as well as the
starting of the application just works fine without any
message popping up.
The issue is that when you take the package from https://github.com/darktable-org/darktable/releases
  as per Pascal's original mail, there is no such installation
  note associated with the file. That was the trap I had ran
  into.
 
I hope that clarifies the issue also for other macOS Apple
  Silicon users.

Re: [darktable-user] Disaster with history stack

[Martin Straeten]

if you have regulary backups of  your ~/.config/darktable directory you can
replace library.db with a recently backup. Then you lose all edits done
after the backup.

if you have regulary backups of  the image directories (& didnt disable
writing xmp files) you can restore the xmp files and let dt check for
changed xmps at startup via preferences setting.
Then you can select to apply the xmp over the database

see:
https://docs.darktable.org/usermanual/4.0/en/preferences-settings/storage/#xmp

Re: [darktable-user] Recommended processing order

[Martin Straeten]

There’s no one size fits it all - if you need information of cropped areas 
you’d better crop late in your workflow, otherwise crop early.
For a beginner it’s ok to recommend late cropping so nothing is out of view too 
early. Hopping back and forward to adjust an improper cropping eats more 
performance than you’ll win with an early cropping. 
An experienced user usually doesn’t need to follow a beginners workflow ;)
Don’t expect a manual to describe workflows for each level of experience…

Re: [darktable-user] Darktable Macbook Pro 13 Monterey

[Martin Straeten]

darktable läuft auf Monterey - bei M1 Prozessor allerdings über Rosetta.
Für selbercompilierer ist auch eine native M1 Version möglich.

Re: [darktable-user] Fwd: Just installed 4.0

[Martin Straeten]

That depends on the time needed to fix the build stuff upstream and then the 
time needed to test the result before and after it’s merged.
Don’t forget, the build stuff must be fine for a whole bunch of Linux derivates 
+ win + OS X ;)

Re: [darktable-user] Marketable 4.0 OpenCL on M1 MacBook air

[Martin Straeten]

in 4.0 opencl is enabled if the gpu significantly faster the the cpu. The 
calculation might not be valid for M1. So you need to enable OpenCl yourself in 
preferences dialog.
Since no developer is using a OS X based system they need as much infos as 
possible. Maybe you can file an issue at 
https://github.com/darktable-org/darktable/issues/new?assignees===bug_report.md=
and provide output of darktable-cltest (run from terminal) or darktable -d 
opencl to help them understand what’s exactly happening.

You can save the changed module order as a custom preset and define this to be

You can export all presets from preferences dialog if you want to have a clean

since darktable doesn't change the original file tags and metadata are just

Re: [darktable-user] Recovering xmp data from Exported jpg files

[Martin Straeten]

Have a look at 
https://docs.darktable.org/usermanual/3.8/en/module-reference/utility-modules/lighttable/history-stack/
 section load sidecar file
If you embedded the history stack into your exported jpg (you need to check the 
option explicitly) then you can use the the exported jpg like an xmp file to 
apply the embedded history stack and shapes to a raw file.

If you’re doing frequent backups you can go back to an older state of 
library.db and export then sidecar files of the affected setback images and 
then after switching back to the recent library.db you can let darktable check 
for updated Xmas (preferences-storage-look for updated xmp files on startup

Good luck

[darktable-user] Re: darktable: physisch vs. physikalisch

[Martin Straeten]

Hallo Bernhard,
Danke für das Feedback.
Beim nachdenken über eine angemessene Übersetzung von „blurs“ tendiere ich dazu 
das physische komplett wegzulassen und das Modul lediglich als „Unschärfe“ zu 
benennen - das erscheint mir passender als Weichzeichnen.
Die Parameter werden dann auch zu Unschärferadius, und „blur type“ wird zur 
"Art der Unschärfe"

Konsequenterweise dann auch Diffusion/Schärfen in Diffusion / Schärfe

Ok so?

Viele Grüße,
Martin

Re: [darktable-user] Retouch opacity

instead of deleting darktablerc you can edit it and change the opacity setting 
for retouch there

Re: [darktable-user] Filmic .. Auto-Tune

[Martin Straeten]

no need to use styles; a custom pipeline order can also be defined as a preset.
See manual 
https://docs.darktable.org/usermanual/3.6/darkroom/pixelpipe/the-pixelpipe-and-module-order/#changing-module-order:

The module order can be manually changed back to either the v3.0 or legacy 
versions using the module ordermodule, which can also be used to define your 
own custom module order presets.

additionally: you need an exiv2 > 0.27.4 built with BMFF support (at least for

mingw64 package has BMFF support built in

Re: [darktable-user] 3.6 not showing images after import

[Martin Straeten]

you may check the import preferences. By default the rating is taken from
camera exif - and some cameras codes no rating as 0. Since the initial
rating filter is set to >=1 the imported images arent displayed.
to exclude an general import error you might change the rating filter to
all to chech if something was imported.

Unfortunatly exiftools doesn’t give helpful hints: there’s also

But this results in massive clipping of the dark areas, losing a whole bunch of

I also checked the raw.pixls.us <http://raw.pixls.us/> image 
(https://raw.pixls.us/getfile.php/130/nice/Canon%20-%20EOS%207D%20-%20sRAW1%20(mRAW)%20(3:2).CR2)
 - unfortunately far away from being norm lit 
Setting black points 0-3 to about 118 -125 seems to give a most neutral result 
(based on the black keyboard )
And it’s also fine for the OPs image, so maybe its a good initial value for 
tweaking ...

Re: [darktable-user] Help needed with Canon CR2 pictures

[Martin Straeten]

No, the OP sent me a cr2 file so i could inspect it.  It seems to be a invalid 
preset for raw blackpoint. This doesn’t affect the full raw, just if sraw or 
mraw is used. There’re no proper blackpoint values provided.

Re: [darktable-user] Help needed with Canon CR2 pictures

[Martin Straeten]

That’s no bug, thats a feature. After importing lighttable shows the embedded 
jpg. in darkroom you can see the raw processed with darktable modules instead 
of the camera internal processing.
If it’s magenta there might be an issue with the default white balance 
settings. I don’t think thats a general issue with darktable since my old 7D 
pics doesn’t show a magenta tint in shadows if processed just with the 
mandatory modules. (scene referred workflow as well as display referred 
workflow)
But 7d is known for being sensitive to highlight clipping, so if you get 
magenta in highlights you might activate highlight reconstruction ,reconstruct 
in lch‘ mode. But better avoid clipping highlights.
Maybe you need to provide a xmp file of an affected image so it’s possible to 
check the settings.

Re: [darktable-user] Missing Histogram

[Martin Straeten]

There was a similar issue on debian 
https://www.mail-archive.com/darktable-dev@lists.darktable.org/msg06154.html
So maybe deleting the user.css in your darktable config directory (in  
/AppData/local/darktable) and unset custom css in preferences might be a 
solution.

Re: [darktable-user] DT 3.4.2 :: see exported formats in lighttable-view

[Martin Straeten]

in the lighttable view all imported files are shown. You can also import
png files - they will be displayed.
Keep in mind that lighttable isn't a real time view onto your diskdrive, so
unless you reimport your directory after exporting png files there these
won't appear in lighttable view.
You can use lua to generate a export, import, group with raw file
afterwards script to achieve this (there's reusable code in
https://github.com/darktable-org/lua-scripts/blob/master/contrib/gimp.lua)

Re: [darktable-user] Still no GUI module order possible?

[Martin Straeten]

it's not just a couple of days - that's just the effort needed to mess up
the UI ;)
you can get an idea on the effort spent just to make module groups
customizable by counting commits (
https://github.com/darktable-org/darktable/commits/master/src/libs/modulegroups.c)
then you might imagine the effort needed to integrate a customizable order
independent of the pipe ...

Thats nonsense. The darktable developers are not just linux developers but
also photographers with much more experience in color science than most
usual Lightroom users. This experience is manifestated in darktable.
If you're just looking for a free/linux Lightroom alternative then you're
on the wrong playground here ...

Re: [darktable-user] Still no GUI module order possible?

[Martin Straeten]

The bottom up order makes sense since in a larger list of modules the modules 
for the color and tonal correction are usually in the upper visible part of the 
screen; the mandatory modules usually not needing tweaks or to be modified just 
once at the beginning of editing are in the invisible lower part...

Re: [darktable-user] Still no GUI module order possible?

[Martin Straeten]

That’s simply not on the prioritization list of the developers: these are also 
users of darktable „eating their own dogfood“ so imaging functionality is more 
important for them then „wasting“ time for stuff that won’t improve their edits.
Keep in mind - it’s not just open source, it‘s also free to be forked if 
somebody will spent a lot of time to implement a different ui.

The best argument against is the absence of a fork having this and being used

Re: [darktable-user] Still no GUI module order possible?

[Martin Straeten]

Even for the favorite list (it’s just a user defined collection of modules) 
it’s useful to know what you’re doing: changing the parameters of a lower 
module affects the upper, especially when using parametric masks.
So there’s really no benefit in having a list of stuff where transparency of 
the process chain is lost... having to switch between module lists just to see 
the „real“ order is quite more annoying then learning it once.

Re: [darktable-user] Still no GUI module order possible?

[Martin Straeten]

the pipeline is the only existing logical order; all other possible orders
are just workflow stuff - without any generalizable logical context.
Your "intuitively" refers to a workflow you're used from other tools. If
you want to use darktable "intuitively" you need to learn about darktables
pipeline...

Re: [darktable-user] Windows Nightly Builds

[Martin Straeten]

No need to file an issue ... known since first upcoming of cr3.
darktable doesn‘t support cr3 since the basic exiv2 library doesn’t support cr3 
yet due to legal implications (canon wasn’t able to give a clear statement in 
this). It seems a solution was found so cr3 might be supported with the next 
version.
You can use cr3 files after converting them to dng.

Re: [darktable-user] Windows: how to safely upgrade from 3.2.1 to 3.4

[Martin Straeten]

Simply install the new software. Theres no need to wipe all stuff if you didnt 
used a development build that messed up things.
You might backup the config directory but darktable usually will create a 
backup of your data.db and library.db
You might also backup the xmp files of your old edits since darktable converts 
these to the current history stack version if you open the image in darkroom. 
But that doesnt change the modules used in the history stack.

Re: [darktable-user] darktable book

[Martin Straeten]

After having a look into the table of contents and some sample chapters it 
doesn’t seem the author is used to the darktable concepts of scene referred or 
display referred workflow. He focusses on the display referred workflow and 
just describes some modules in darktable 3.0. It seems to be a very generic 
concept. There were a lot of changes in 3.2.1 and 3.4
In my opinion https://darktable-org.github.io/dtdocs/ 
 is ways better if you really want to 
understand what’s happening in the modules and also the translated old style 
manual  https://darktable.gitlab.io/doc/de/ 
 or the pdf version.

One of the basic articles is translated into German 
https://www.bilddateien.de/blog/2020-01-26-darktable-3-workflow-lab-oder-rgb.html?q=darktable
 

 There’re also German translations of the release notes on this site …

Re: [darktable-user] Where are Collections stored?

[Martin Straeten]

file locations are stored in the library.db.
Id is an integer and the location a varchar(1024) 
From the reference: 
INTEGER. The value is a signed integer, stored in 1, 2, 3, 4, 6, or 8 bytes 
depending on the magnitude of the value.

So i doubt you reach this limit with your library.
You may run darktable -d sql to see if there are failing database activities ...

You can use zone system even it’s deprecated. You just need to put in into the

Seems you had edited the other images earlier and removed them from darktable

Re: [darktable-user] Increase lighttable performance

[Martin Straeten]

If you don’t use the embedded presets then each image has to be processed with 
the default workflow. Once processed, they’re cached. 
So it’s worth to tweak your OpenCL settings

Re: [darktable-user] How to delete a film roll ? + I can`t find "Cache/Darktable" on my Macs

[Martin Straeten]

The cache is in ~/.cache/darktable directory
But if it crashes after importing a filmroll, then it’s usually not the cache 
but the library containing stuff darktable can’t process.
You might rename ~/.config/darktable to ~/.config/darktable.old and start from 
scratch. 
If that doesn’t work, you can start it from terminal with
/Applications/darktable.app/Contents/MacOS/darktable -d all
to get an idea whats happening just before the crash
If dt crashes while importing a specific image with already existing xmp file, 
then it makes sense to open an issue at 
https://github.com/darktable-org/darktable/issues/new?assignees===bug_report.md=
 and provide the xmp.

Re: [darktable-user] color lookup table

[Martin Straeten]

It works as designed: 
You can change L, a, and b independently since - saturation is no independent 
parameter in Lab
You can enter precise values with right mouseclick on the slider

BTW try a look into the manual: 
https://www.darktable.org/usermanual/en/module-reference/processing-modules/color-look-up-table/

Re: [darktable-user] Darktable is slow

[Martin Straeten]

usually opencl isn’t activated on osx since there might be issues with intel 
graphics. But you can activate it in the preferences - if opencl is available 
on your machine.
Maybe you further need to tweak your opencl settings (see 
https://www.darktable.org/usermanual/en/special-topics/opencl/)

Sometimes it needs several darktable starts to build all opencl kernels ...

Re: [darktable-user] Geeqie RAW preview as starting point for DT

[Martin Straeten]

Do have an idea, what geeqie is doing with the raw file? Simply displaying the 
embedded jpg?
In lighttable dt displays the embedded jpg by default - until you process it - 
then everything is based on the raw data.
To achieve exactly the same result as the embedded jpg darktable must include 
the whole im camera processing stuff the camera manufacturers keeps as their 
secret.
So don’t expect darktable being convinced ;)

Re: [darktable-user] No Opencl on macOS 11 (Big Sur)

[Martin Straeten]

For osx it’s very important to tweak opencl preferences in 
.config/darktable/darktablerc.
I found my macbookpro 16 gives best performance if used in opencl mode 
‚default‘ with forcing full pixelpipe being processed by amd gpu (1) and 
preview pixel pipe with cpu (-1) 
(opencl_device_priority=1,0,*/!1,!0,*/1,0,*/0,*/*) in combination with 
performance mode (new with upcoming 3.4) and reduced resolution of preview 
image. The other opencl modes prioritized the on chip gpu (0) at cost of speed 
...

You can evaluate the processing time and used gpu device runnig darktable from 
terminal:
darktable -d perf -d opencl | grep -e'processing took' -e'using device'
Happy tweaking ...

To enable opencl on osx 11 use the workaround described at 
https://github.com/darktable-org/darktable/issues/6918#issuecomment-727595566

Hi Marc,

when I started dt two years ago for the first time on my new iMac-5k-screen, in 
full screen as I had been used to on my former HD screen, I was shocked by the 
slow performance. My first idea was to blame Apple. But when I did realize that 
full screen even extended the pixel size of my pictures I changed the mode of 
my operation. I reduced both the dt window and my distance from the screen, put 
my reading glasses on and eventually got a decent dt performance.

The point is that you shouldn't so much pay your attention to higher resolution 
but to more free screen space. What's the use of a 5k screen when you remove 
yourself from it so that it looks the same as a HD screen? We don't talk of UHD 
movies, do we.

All the best

Re: [darktable-user] Getting machine JPG colours in RAW editing

[Martin Straeten]

You might use this: 
https://pixls.us/articles/profiling-a-camera-with-darktable-chart/
But this approach isn’t useful when using filmic, since color lookup table and 
tonecurve are mandatory.
Best solution to get nikon colors is using the software provided by nikon ;)

the database just stores the history stack like it's contained in the xmp.

Re: [darktable-user] Can DT be loaded onto MAC running Mojave OS

[Martin Straeten]

Its not necessary to upgrade the operating system. On first start darktable 
just updates its own databases in ~/.config/darktable. These database contains 
overall settings of styles, presets etc. and metadata of imported images and 
their history stacks.
If you’re afraid of losing data you can do an additional backup of the 
directory yourself.
Darktable 3.2.1 runs fine on Mojave ...
