I have found library.db and library.db-pre-3.0.0 in the same directory,
which was not created by myself for sure, so I think my guessing was
not so wrong.

Let's see, if the error appears again, at the moment I have no picture
to delete to test it.

Patrick, the mouse wheel works and there is no difference, if I press
ctrl or alt or both. With a lot directories ;-) the wheel is not
comfortable too. Imagine I have 100s of directories and I have to
choose one in the last third.

BTW, can you explain the difference between folder and directory, for a
non-native English speaker I cannot see a difference. At the end it
counts for me, that it does what I want.

Just to inform the readers about my simple solution, where you can
replace medit with your editor. I am aware that the solution Stefan
describes has a lot of advantages, but I think I do not need it.

sudo medit /usr/share/darktable/themes/darktable.css

In Ubuntu I changed line 163 to
font-size: 9pt;

It didn't work to change e.g. to 0.5em from 1em, but this is not a
problem. I am happy for the moment.


Is there a possibility to make scrollbars a little bit broader?

Thank you all for your answers, I read here of the problem, when people
were compiling dt 3, but never thought that a repo-package has not an
easy way to set the fonts.

Is there a feature request for better setting the font size?

I changed already dpi with my XFCE, so this is fine for the most
programs, but not all and dt looks now unusable. So modifying dt may be
tricky, but now I know the possibilites.

Was there a conversion of darktablerc from 2 to 3? Did dt 3 install a
fresh darktablerc? Maybe I should start from a default darktablerc.

It depends on your motherboard, but I had to switch to a newer kernel

Yes, my motherboard takes longer to check, than the system boots.

I bought one from MSI which is silent, when not heavy used, a little
bit more expensive, payed about 220€ before Christmas. I hear it when I
do a export, but not when I do editing with DT.

6GB MSI GeForce GTX 1660 Ti ARMOR 6G OC Aktiv PCIe 3.0 x16 (Retail)

Don't forget to check your system, if everything is fine. I had very
strange behaviours. And test a few times, because the 1st time, modules
have to be compiled for faster local usage.

I am using Ubuntu 19.10 now, but I am not the thread startener.

Oh yes, some years ago.
Some months ago with Ubuntu 18.04 a GTX 1030 was slower(!) with opencl,
but now the 1030 is faster, about 2x without opencl, while the 1660 is
about 10 times faster with opencl. Of courese this depends on the test
scenario. I used the testfile bench.srw from the phoronix test-suite.

It also depends a lot which nvidia-driver you use. It worked without
problems, when I installed the nvidia-driver during installation, if I
installed it afterwards I got mixed versions.

I never got suspend to ram working acceptable, had strange problems to
wake up the pc.

Even that I couldn't do always. Going to a terminal (Ctrl-Alt_F1)
blindly and pressing ctrl-alt-del

That's true, while the bios-version can be very important, especially
with a x570-chipset.

Similar here,

3700X with 32GB RAM, but I think there is no difference to 16GB doing
tests. It always depends which modules you use with darktable.

I think the RAM of the graphics adapter is a _lot_ more important.

I use a GeForce GTX 1660 (no TI!). There is no noticeable advantage
with the TI. If you want it faster you have to spend a _lot_ more money,
as already mentioned more RAM of the graphics adapter reduces tiling
and that saves a lot more time than a faster GPU.

We had this discussion a while ago doing tests with cli, my pc was a
lot faster because it did not use tiling.

So if you do not very complex tasks with DT, the 1660 is the sweet
point IMHO.

So do I have to define 0x003f and 0x0207 in a certain way, where the

[darktable-user] GeForce 210 without opencl faster

[Аl Воgnеr]

I wonder why an old pc with a GeForce 210, AMD Athlon II X2 270, 8G RAM
is slower using opencl.

darktable 2.6.3~git2.22c690a53
Fresh installation of the pc, using default darktable-configuration

$ darktable-cli bench.srw bench.srw.xmp bench.jpg --core -d perf -d
opencl

[opencl_init] device 0: GeForce 210 
 GLOBAL_MEM_SIZE:  1024MB
 MAX_WORK_GROUP_SIZE:  512
 MAX_WORK_ITEM_DIMENSIONS: 3
 MAX_WORK_ITEM_SIZES:  [ 512 512 64 ]
 DRIVER_VERSION:   340.107
 DEVICE_VERSION:   OpenCL 1.0 CUDA

0.254144 [opencl_init] FINALLY: opencl is AVAILABLE on this system.

227,385925 [dev_process_export] pixel pipeline processing took 225,369
secs (165,316 CPU)

I do not find "blended on _G_PU" in the log. Log attached.


$ darktable-cli bench.srw bench.srw.xmp bench.jpg --core
--disable-opencl -d perf

76,490890 [dev_process_export] pixel pipeline processing took 74,577
secs (144,522 CPU)

BTW:
GeForce GT 1030: 17,770 secs (26,050 CPU) / 37,168 secs (281,707 CPU),
AMD FX-8320, 8G RAM
So with a GT 1030 it is getting about 2 times faster using opencl.

The download was faster finished than expected. With "very fast GPU" I
got af a reboot of the pc:

8,123046 [dev_process_export] pixel pipeline processing took 0,616 secs
(0,967 CPU) [export_job] exported to `ff_02.jpg'

So it was slower, but these are so short times and because it is so
short, its meaning is not reliable. If you want a log, let me know.

Done, don't know when I can do a comparable test. At the moment a big
download is running.

No idea, how I got the values above.

What does cache_memory influence? No idea, from where this value comes.
I could _could_ calcalute this value a long time ago after a
recommendation, I don't remember this.

How opencl_checksum is calcaluted, this is a value from a rc-file with a
total different graphics card. (Geforce GT 1030)

No, the files from https://math.dartmouth.edu/~sarunas/bench_raw/ are
files to compare with others. I use only a few modules, bench.srw uses a
lot more modules than I normally use.

Hard to say, if I found a typical fullformat excample, but with my own
fullformat example I see:

7,393864 [dev_pixelpipe] took 0,116 secs (0,300 CPU) processed `Gamma'
on CPU, blended on CPU [export]

All others are:
"blended on GPU [export]"

7,393968 [dev_process_export] pixel pipeline processing took 0,608 secs
(0,915 CPU)

Complete log is attached.

So my ff-36MP-photo is a lot faster calculated.

My goal is to avoid to copy stupid settings from the old pc.

Interesting is:
Spitzlicht-Rekonstruktion' on GPU, blended on GPU [export]

With the bench.srw it was calculated by the cpu. So the use of the cpu
depends on something and not on the coding of the module itself.

So my question, if some of these values should be changed, because the
new system is a lot more powerful:

cache_memory=1073741824
maximum_number_tiles=1
metadata/resolution=300
opencl_checksum=3732205163
opencl_device_priority=*/!0,*/*/*
opencl_mandatory_timeout=200
opencl_memory_requirement=768

1 sec difference does not matter a lot, 10 sec do, especially I don't

I tried "opencl_memory_headroom=100"

10,485934 [dev_process_export] pixel pipeline processing took 3,299
secs (8,980 CPU)

So there is no big difference.

Next test:

opencl_memory_headroom=300
opencl_use_pinned_memory=TRUE

9,945665 [dev_process_export] pixel pipeline processing took 3,297 secs
(8,961 CPU)

My starting value was 3,306 secs. So opencl_use_pinned_memory doesn't
change the speed a lot too.

Thanks Ulrich, but isn't there always the same difference? I discuss
this bench.srw because it is available publically and uses a lot of
image manipulations. Actually I use bigger files with 36MP FF, but with
a lot less modules, especially not mdules for advanced users.
`Spitzlicht-Rekonstruktion' (highlight correction) I use very often,
but I think I never used `Tonemapping'

After reading 
https://www.darktable.org/usermanual/en/darktable_and_opencl_amd.html I
am getting very unsure.

I do not have any variable in ~/.config/darktable/darktablerc containg
GPU.

 opencl_memory_headroom

This parameter controls how much graphics memory (out of the
reported one) darktable should leave UNTOUCHED for driver and
display use. As for AMD/ATI devices we anyhow only can get half of
the available RAM it's safe to set this to zero. So all of the
512MB can be used by darktable.

So should opencl_memory_headroom be a small value and 300 is fine? 3000
is the half memory of my GPU.

I attach my complete darktablerc.

[darktable-user] OpneCL and Memory optimization (6G GPU, 16-32G system)

[Аl Воgnеr]

I think it is not a good idea to mix problems of another person in 1
thread. So I start a new one.

In the family we have 2 pcs, which are used with darktable
2.6.3~git2.22c690a53 (from Suse OBS), but the distro is XUbuntu 11.10.

Both pcs have a GeForce GTX 1660 (6G, 5941MiB), AMD Ryzen 7 3700X. 1pc
has 32G RAM and the other 16G.

DT is the only program at the moment, which uses opencl.

/usr/lib/xorg/Xorg 586MiB
xfwm4  4MiB

After starting darktab le Xorg memory increases a little bit

/usr/lib/xorg/Xorg 618MiB |
xfwm4  4MiB
/usr/bin/darktable 73MiB

At the moment I have:

$ grep -i opencl ~/.config/darktable/darktablerc
opencl=TRUE
opencl_async_pixelpipe=false
opencl_avoid_atomics=false
opencl_checksum=3732205163
opencl_device_priority=*/!0,*/*/*
opencl_disable_drivers_blacklist=false
opencl_enable_markesteijn=true
opencl_library=
opencl_mandatory_timeout=200
opencl_memory_headroom=300
opencl_memory_requirement=768
opencl_micro_nap=1000
opencl_number_event_handles=25
opencl_scheduling_profile=default
opencl_size_roundup=16
opencl_synch_cache=false
opencl_use_cpu_devices=false
opencl_use_pinned_memory=false

$ grep -i memory ~/.config/darktable/darktablerc
cache_memory=1073741824
host_memory_limit=1500
opencl_memory_headroom=300
opencl_memory_requirement=768
opencl_use_pinned_memory=false

Which values should be changed? This darktablerc is from an old pc,
optimized for a 32" monitor.

I changed from 300 to:
opencl_memory_headroom=3000

darktable-cli bench.srw bench.srw.xmp bench.jpg --core -d perf -d opencl

before with 300:
9,990739 [dev_process_export] pixel pipeline processing took 3,306 secs
(8,786 CPU)

with 3000:
10,247914 [dev_process_export] pixel pipeline processing took 3,381
secs (9,029 CPU)

It is nearly the same, actually it was a little bit slower with 3000.

Attached is a full log, using "opencl_memory_headroom=3000"

I am interested for settings which make this test faster. I restarted
dt, but not X.

You are right, always when I used Radeon *I* had big problems, so I
didn't use it in the last years, probably longer than 5 years.

Yes, elstaci is correct. OpenCL support for CPU devices has been
dropped starting with Adrenalin 18.8.1. 

Such things are very irritating to me.

Can anyone tell me if darktable can use cpu *and* gpu at the same time
to export photos? I know that there are modules which cannot use the
gpu, so the cpu is needed, but does a better cpu improve speed if the
gpu is used for a module?

Hi,

after searching a lot in the web I decided to buy a NVIDIA Corporation
TU116 [GeForce GTX 1660]. Note: the more expensive TI is not remarkable
faster, nearly the same speed, depends on the photo. I think this card
has the best price-value. If you are not adventurous with Linux, use
Nvidia and / or search for AMD and troubles. It doesn't help if you
read it will get better and what could be maybe. Note the differences
if you compare. At the end your system must work now and not maybe some
day, IMHO the cpu is not so important, if you compare the GPU.

Would be interested how long the RTX2060 takes with the bench-file.

Try to install the phoronix test suite to get compareable test-files
and do something like below:

You can download the bench-file here, but the phoronix suite contains
more test files to compare:

So using the GPU is about 5 times faster for me.

Read for more tests:
https://math.dartmouth.edu/~sarunas/darktable_bench.html

What I found out, that it is getting a lot more expensive, if you
want significant more speed, but I cannot give you an advice what do
use, if you want to spend less money. Ask always for people who use
this card really and don't talk about theory. There are a lot of
details. It didn't work for me out of the box, I had to install some
packages, which I had to guess. You have always to check which
operating system / graphics driver is needed. In my case I had to use
Ubuntu 19.10. Note this distro uses a very outdated exiv2-version as
discussed in another thread here.

Thanks, for a 1st test it looks good and it seems to work. But, I do
not own this camera and there was a strange behavior with darktable.
After I configured the photo manually, dt seems to remember this, even
if the xmp-file was deleted. Only a newer used photo showed the manual
lens configuration.

Since I do not have a test photo, which was never used, I cannot say it
works for sure, but I removed the xmp-file and cleaned the database. It
is different to my experiences.

I will give you feedback again, when I get a new test photo, can take a
while, because the owner is ill at the moment.

Good to know.

Are you sure to use

1.5

After searching the net, I found

1.53

And I have no idea, if this makes a difference.

https://www.digicamdb.com/specs/ricoh_gr-iii/

Sensor diagonal = 28.21 mm
Crop factor = 43.27 / 28.21 = 1.53

Do you talk about Ubuntu? Other linux distris have a newer exiv2.

I am "fighting" with thix exiv2 problem since 2 years and it looks like
the problem will exist for 2 more years. Unfortunately it is not so
easy for me to change the distro.

exiv2 0.25-4ubuntu3 (s390x binary) in ubuntu focal
Focal will be released in 2020.04 and is the coming LTS-version.

Debian uses exiv2 0.25-4 since a very long time and 0.27.2-3 is in
experimental (see https://packages.debian.org/search?keywords=exiv2 )

So this means the next long time release of Ubuntu will still have 0.25
including all the troubles with new lenses.

The reason for the problems are API changes from 0.25 to 0.26 maybe,
but other distros managed the change.
https://www.exiv2.org/changelog.html

On the other side:

https://www.exiv2.org/manpage.html
Exiv2 can read an optional configuration file ~/.exiv2 on Unix

https://dev.exiv2.org/issues/0001035
I'm going to accept this assignment for v0.26 as we can't consider this
for v0.25

https://dev.exiv2.org/boards/3/topics/3017
However, Digikam and Darktable doesn't apply any lens correction, cause
my lens is identified incorrectly ...
You can fix this for yourself. In Exiv2 v0.26, you can put the name of
your lens into the file ~/.exiv2 This is discussed here.
http://dev.exiv2.org/issues/1328

So there is no solution before 0.26.

There are a lot of new lenses which lead to problems for Ubuntu
users. I think **4** years are a very long time of problems and
therefore my question, why a simple lens identification can make so
much trouble and if there is not an alternative? Eg I can imagine a
darktable configuration, use exiv2 or exiftool for lens identification.
This should not be so much of coding.

There will be new cameras and lenses always and there should be an easy
workaround for users of new lenses. I like dt and would like to use it,
but I have to look for another program if my equipment is not
supported. But I will try a lot to use my fav dt.

My lenscorrection files from Ubuntu 18.04 do not work out of the box in
19.10, but I think I will get it work again (1 already works again,
very small changes are necessary and it is guessing what could help). I
did things, which I would never do normally. I replaced the xml-files
for the brands I use with the newest one from git, changed it from
 to . So a lensfun
update will replace these files. On the other side, I am pretty sure,
there will be no update and if, it contains the new lenses hopefully.
After the files from git my Pentax K-1 was recognized correctly, before
it was recognized as K-S1 (a known bug since a long time)

Before I tried:
# lensfun-update-data 
Reading http://lensfun.sourceforge.net/db/versions.json …
Reading http://wilson.bronger.org/lensfun-db/versions.json …
Info: No newer database was found for last installed Lensfun.

This didn't help for my lens-recognition.

I tried to compile eviv2 and ended on dependencies / not available other
packages. Any help is welcome. Please point me to the exact
download-link, which I should use with Ubuntu 19.10. I gave up with
Ubuntu 18.04 already because of dependency problems.

I searched for repos of course

https://www.exiv2.org/download.html does not show an Ubuntu 19.10
specific repo. I have downloaded
https://www.exiv2.org/builds/exiv2-0.27.2-Linux64.tar.gz and set the
environment, so I can use a newer version in the shell, but this
doesn't help with dt.

Maybe there is an exiv2-repo for Ubuntu in OBS, but I could not find it.

At the end I am very unsure if a newer exiv2 helps to solve my problem
with the Ricoh GR III, but for sure with other unknown dslr-lenses.

I try to attach a small screenshot, which shows my Ricoh problem.
Every things works, except that I have to select the lens manually.
This GRIII has a fixed focus lens and is a compact camera with an APS-C
sensor. It doesn't matter how I call the lens. Exiftool reports "GR
Lens". If I call it "fixed lens", I have to select this name.

IMHO it should be enough that the camera is recognized. The camera is
recognized automatically as it should. So why a lens selection, if
there is only one possible?

[darktable-user] Are there Ubuntu-19.10-Users with manual added lenses?

[Аl Воgnеr]

I try to use DNG-files from a Ricoh GR III with
darktable 2.6.3~git2.22c690a53 (from OBS) and Ubuntu 19.10

GR III-lens is not recognized automatically, but the camera itself is.

After discussing this in the lensfun-maillinglist it could be that is
not very much related to lensfun, but maybe to Ubuntu or darktable.

The problem with Ubuntu is, that exiv2 is very old with this distro.
Even the coming Ubuntu 20.04 uses the very old exiv2 0.25, while 0.26
is needed at least for a manual lens id configuration, although it
looks like that this camera has no lens id using exiv2 0.27.2

This exiv2-problem exists for about 2 years now and will exist 2 more
years with Ubuntu. So there are 4 years for some new lenses to wait. As
said, it could be, that with this camera there is no eviv2-problem, but
for sure with other new dslr-lenses.

Is there a way, that darktable uses exiftool instead of exiv2? The
decision is hard, but I don't want to change the distri to get a newer
exiv2 and compiling looks to be not so easy (glib2).

So I am posting the problem with the Ricoh GR III in this list too.
Maybe someone can help.

My lens-configuration is based on this post:
https://github.com/lensfun/lensfun/issues/895

I have put the configuration file in ~/.local/share/lensfun

All the variations I tried, worked manually, but not automatically.
This is my latest trial:

-




RICOH IMAGING COMPANY, LTD.
RICOH GR III
RICOHGR3
1.53



RICOH IMAGING COMPANY, LTD.
RICOH GR III
GR Lens
RICOHGR3
1.53

  ...   


-

In other words this means, I have to choose the lens every time
manually, while the camera is recognized automatically.

I have discussed this problem a few times with Sigma lenses in this
list. There are a lot of Sigma leneses, which are reported as Sigma
only.

See eg:
Subject: Re: [Lensfun-users] Adding new corrections and creating
corrections  from user submissions Date: Thu, 14 Jun 2018 23:44:14 +0200

The first problem is, that the dt-repo for the latest Ubuntu 18.04,
doesn't contain an exiv2-version, which supports this.

The 2nd problem is, that lensfun uses this recognition and how
lensfun-corrections has to be defined in such a case.

Same situation, with this lens:



Pentax
HD Pentax-DA 70mm f/2.4 Limited
smc PENTAX-DA 70mm F2.4 Limited

Without the last line, I am told to choose the lens manually using the
corrections from the repo-installation (not the update).

I am a little bit confused, because the same lens queried by exiftool
says sometimes, it is the HD an then the smc lens. It is the HD lens
with the red ring. exiv2 says too it is the smc-version with a test
file.

I understand that they sell a lens with an old ROM, but I do not
understand, why I remember a query, where HD was the result.
Unfortunately I cannot find a file, which says it is the HD lens. Maybe
some software changed the file then.

Sorry, if I write "maybe". If I do this the correction works, otherwise
not.

Not sure, I discussed this already in the lensfun-list. It should, but
my experience is, that the "trick" with  helped very
often, but not always.

This thread was originally started as crossposting to the lensfun-list
and the lensfun people have subscribed the list. If I am pretty sure,
that it is correct, what I am writing and if I detect a bug, I will
send them a mail of course.

In the meantime I have some lenses corrected, which did not work
before. I do not use "update" anymore and then it works in
~/.local/share/lensfun if I do not use a version. I decided to create an
own file there for every lens which doesn't work. I am still fighting
with the Pentax DFA 24-70. It doesn't help to use the correction file
from 16.04 (which worked). My next step will be a local exiv2-info-file.

Ok, I am a very little step further.

This lens is recognized now after installation, but if I excecute
lensfun-update-data as _user_ (I never did it since purge as root) the
lens is _not_ recognized.

After I removed the files in ~/.local/share/lensfun/updates/version_1
the lens is recognized again.

I want to create my own corrections as with Ubuntu 16.04 (where
a lot more lenses worked after I created my own corrections with
little changes to existing ones), so I would like to know, how the 1st
lines of a correction file should like like because there was a change
with lensfun 0.3

Then I will try it in ~/.local/share/lensfun

I have no idea too, maybe something is misconfigured, I never did

The .local files are always owned by the user, but I want to add, that
it is a link to another partition. This worked perfect with Ubuntu
16.04. IMHO it should be enough permission, so a user can read it. But
in this case, the user can write it too. With 16.04 another user could
use it too.

No this was my suggestion for APS-C, but ther is one for cropfactor 1,
which I posted earlier in this thread.

At the moment I am talking only of automatic correction.

Yes, and therefore I added a line:


Sigma
Sigma 70-300mm f/4-5.6 DG Macro

Sigma 70-300mm F4-5.6 DG OS

Sony Alpha
Sigma SA
Pentax KAF2
Canon EF
Nikon F AF
1

This works, if I remove all other Sigma 70-300mm entries.

BTW I have another lens, which is not recognized, but was with
Ubuntu 16.04.

Tamron SP AF 28-75mm F2.8 XR Di LD Aspherical [IF] Macro

I can provide a sample tomorrow, if you want.

So I don't have an older lensfun, like Tobias suggested. But I fear
there will be no older lensfun installed.

If you think, it makes sense, I can purge lensfun and darktable and
install again.

Do you have files in /var/lib/lensfun-updates/version_1/ or in other
words, did you execute lensfun-update-data as root? Maybe if the update
is done as root, files in ~/.local/share/lensfun are ignored?

On the other hand, there is a file with cropfactor 1 for this lens in
the lensfun-database, but this is a lensfun-configuration problem IMHO.
The posted configuration works for me, if the other similar lens
corrections are removed.

I also wonder which lensfun correction is used, if there is a 2nd
correction in the file.

I think this depends, if you execute lensfun-update-data as root or as
user. I executed it as root.

[darktable-user] lensfun priority troubles with Ubuntu 18.04

[Аl Воgnеr]

gimp-lensfun 0.2.4-1
liblensfun-bin 0.3.2-4 ii
liblensfun-data-v1 0.3.2-4 ii
liblensfun1:amd64 0.3.2-4 ii
python3-lensfun 0.3.2-4

So everything is 0.3.2-4, except for gimp which is 0.2

I use lensfun with darktable 1:2.4.3-0pmjdebruijn1~bionic 

I try to get a Sigma 70-300mm F4-5.6 DG OS working with _fullformat_ and
darktable 2.4.3. The lens works with APS-C, but not with fullframe
after the repo-installation. The correction suggested by me with a
comment in the xml-file was used with APS-C (and worked).

The correction below generally works for APS-C and FF, but it is not
recognized in .local-folder. It is a different correction that I
suggested. The correction below is for FF.


So there are 3 place where a correction can be:

/usr/share/lensfun/version_1/
/var/lib/lensfun-updates/version_1/
~/.local/share/lensfun

What I tried with different headers and maybe there is something wrong.

I removed _all_ correction for Sigma 70-300mm in
/usr/share/lensfun/version_1/ and
/var/lib/lensfun-updates/version_1/

So the only correction then was in ~/.local/share/lensfun. Darktable did
not recognize the lens.

I added the correction below in /var/lib/lensfun-updates/version_1/,
but have kept all existing 70-300 corrections. Darktable did not
recognize the lens with FF.

Then I removed _all_ 70-300 corrections and added the correction below
in /usr/share/lensfun/version_1/. Darktable recognized the lens with
APS-C and FF.

So this will work until the next update only.

I have backuped the original slr-sigma.xml, so I can restore them easily
for tests.

Please note, I added:
Sigma 70-300mm F4-5.6 DG OS
to the existing FF-correction





Sigma
Sigma 70-300mm f/4-5.6 DG Macro
Sigma 70-300mm F4-5.6 DG OS

Because I have 1 file, where lensfun works here too with this lens and
my system! See the websample-screenshot. It is a raw-file with a DFA
24-70 too. The webfile recognizes the lens on the left side and on the
right side for lens correction.

Maybe it are different raw-formats.

Mine:
[MakerNotes]0x0027 DSP Firmware Version: 1.43.29.23

Web:
[MakerNotes]0x0027 DSP Firmware Version: 1.00.00.00

So it could be, that there is a newer format, which doesn't work with
my dt / exiv2-version. I am thinking of linking the newer lib-version
to the old 14-version. Maybe this works, but did not try it.

I am convinced to solve the left side in dt first. I must see the
correct lens there and then we go on to lensfun, if needed (on the
right side)

Compilation of exiv2 was no problem, but I fear it is getting more
complex with dt. No idea which options are possible, but maybe I can
define my compiled exiv2-version when building dt.

Maybe I just have to wait until a new version for dt is published.
There are 2 possibilites, the suse-repo for xubuntu (actually I use
xubuntu) and the ubuntu version.

Is there a readme or what else for compiling dt?

I still do believe, it is not a lensfun problem, first dt must
recognize the lens. I am pretty sure that it works with lensfun, when
the lens is recognized by darktable and dt uses the compiled exiv2
version, and not the old one.

Maybe I should remove the Ubuntu-dt-version and compile dt myself, but
that takes time, which I don't have in the next time.

Unfortunately there is nothing for Ubuntu 18.04, maybe I have to wait.

I have installed Darktable Unstable PPA, but this is the same as the
stable version at the moment.

I am not so familiar with irc. Maybe I should file a bug report because
of the different behavior. I accept, that something doesn't work, but
it is hard to understand why some files work and some not.

The pngs are screenshots, that show, that my system recognizes the lens
of a raw file from the web, but not my files. That is so confusing.
Check the left side of the webfile and my files.

So what can I do with my ubuntu system?

I did not mention any delay, this was another user probably. The change
to the next file can take a while, maybe 2-5 secs, but this is a
36MP-file and I think this is normal.

If i try to remove libexiv2-14, darktable will be removed too.



Beside that,

here are my sample-pictures, including screenshots, where you can see,
that the web sample recognizes the lens, but with my files, the lens is
not recognized.

It depends on your equipment. If exiv2 recognizes your equipment you
are happy ;-) I didn't find any problems with image manipulation.

I know a little bit more in the meantime.

IMO one big problem is the exiv2-version. Bionic contains the 1 year
old exiv2 0.25-3.1, but only version 0.26 allows to define own lenses
and 0.26 recognizes more lenses, if you search the web.

See eg http://dev.exiv2.org/boards/3/topics/3017

So the first thing is to get exiv2 0.26 work. If darktable shows a lens
like 0x you have to define .exiv2 in the home directory. If the
lens ic recognized then by darktable, you must check if lensfun
recognizes it. I have lenses which are recognized by dt (on the
left panel), but not on the right side (lens correction), although a
lensfun-file exists.

I have to do more tests, to find out, why a lens which worked with dt
2.4.3, but not with Bionic anymore. Hopefully it is a syntax
problem of the lens file, which has changed. Again, the 1st step is to
get exiv2 0.26 work.

[darktable-user] Disappointed by new Ubuntu version Bionic

[Аl Воgnеr]

I had big problems with Ubuntu 16.04, but now with Ubuntu 18.04 it is
getting more worse.

This is the version I use at the moment with Bionic (18.04):

darktable 1:2.4.3-0pmjdebruijn1~bionic

liblensfun1:amd64 0.3.2-4
 
exiv2 0.25-3.1

First I tried the Ubuntu-repo-version, then I changed to
ppa:pmjdebruijn/darktable-unstable which is the same at the moment.


In 16.04 (Xenial) I used liblensfun 0.2.8-3. What comes in my mind is,
there was a syntax change, so maybe this has to be checked.

There is still the bug e.g, with the Pentax K-1, which is recognzized as
K-01. Well, this can be solved easily, but I have problems now with
lenses, which worked already. I start an own topic, for the lens
problem.

Which experiences did you make with Bionic?

It looks like it is a lensfun-bug.

I removed the K-S1 part in /usr/share/lensfun/slr-pentax.xml and
deleted my own file ~/.local/share/lensfun/k1.xml. The K-1 is
in /usr/share/lensfun/slr-pentax.xml already. Now the K-1 is recognized

I have photos from a Panasonic DMZ-FZ20 and would like to know if noise
reduction is applied with all ISO 400 photos.

ok, there is eg:

  darktable:operation="lens"
  darktable:enabled="1"

I am not sure if the following row is important too.

If the line does not exist, there is no lens correction. In this case
all Canon G7 photos will be shown, because there is no lensfun entry.


cat *.xmp | grep lens
  darktable:operation="lens"
  darktable:operation="lens"

cat *.xmp | grep lens | wc -l
2

ls *.xmp | wc -l
2

So if the filmroll does _not_ contain photos with different cameras /
lenses, which are not supported by lensfus, this could be a hint if
there are photos which have no lensfun correction. But at the moment I
have no idea how to display this / these filename(s).

I mean the latter case. My filename includes the lens, so it would be
easy to filter, but that is not what I want.

Imagine you have a filmroll with 200 photos and complex image
manipulation. Every photo takes 5 seconds until it is loaded. So it is
very time consuming to check the lens correction by clicking on every
photo.

A similar situation is noise reduction. A selection with camera and ISO
would be interesting.

My wish would be 3 technical criteria for a selection in combination
with a dt action.

Maybe analyzing the xmp-file could be a workaround. It looks like, if
there is no lens correction, the word lens cannot be found in the
xmp-file. But it is getting complicated, if there are lenses, where no
lenscorrection exists. I didn't find the lensmodel in the xmp-file.

I don't use this camera anymore, but I think I can get it for a few

When I check
https://github.com/lensfun/lensfun/blob/master/data/db/compact-canon.xml
it is the same Canon Powershot G9 __X__ has some lens date, but there
is no G9.

Of courese I will do testing, when you tell me where to get a lens

Ok, but this doesn't answer my question, why it makes sense to do this.
IMHO this is useless, if no lens description is available.

Did you see that I posted the beginning of the lens description of the
Canon G7 __X__ ? There is none for the G7 (without X). These both G7
are totally different. The G7 is not a DSLR camera, it is a top compact
camera.

I asked it, because some G7 user could tell me, it works fine for him
and I have something wrong in my system. Many years ago the G7 was the
top model of Canon's compact cameras.

I agree, that lensfun should collect all the lenses (at the end). The
question is, if darktable should offer a quick solution for alias
lenses, which the user can define *immediately*. IMHO yes.

So if darktable allows alias lenses by the user, which are not in the
lensfun database, the user should be informed, that the dt-alias-lens
is now available in the lensfun database, so that the dt-alias can be
removed. Actually it is not so important if it is an alias lens. If I
think a workaround could be to use the correction of lens B for lens A,
I should be able to do this.

IMHO the xmp-file should contain the lensfun-lens, and not the
alias-name, which lensfun doesn't know at this time. This is the same
as I do manually now.

I fear this isn't included with Ubuntu Xenial as well as
g-lensfun-update-data. In earlier discussions nobody mentioned this.

Thanks for this discussion! I think this is a very important topic how
to manage not recognized lenses and cameras. As you already mentioned,
camera aliases are important too. My lens is recognized e.g., but the
camera not, so I have to define a camera for every image, although all
Pentax-APSC-DLSR have the same data.

AFAIK it depends on the sensor size, so why not a suggested sensor size
if the camera is not available. Eg. it is recognized that the photo was
taken with a unknown Pentax-DSLR, so dt should make a suggestion for
Pentax APS-C, which can be predefined in preferences.

Well, I am not alone, and there must be a way to get an acceptable
solution.

Is there already an official bug / wishlist entry for darktable?

So why not let the user do the solution?

I would like to see the following in dt:

dt-preferences: define used cameras and lenses in a _flat_
alphabetic list.

If you need to define a camera manually, like i have to do with a KP,
it is a lot of klicking. I think the most people have less than 10
cameras and less than 10 lenses, so a hierarchical menu for the owned
equipment is time consuming. The list will grow, because some day
everyone buys a new camera and keeps the old photos. But nevertheless a
flat menu will be the best for manually choosing.

alias lenses of existing lensfun-lenses in dt.

notice / warning in dt if an alias lens was added to lensfun.

The selected alias lens has to be written in the xmp-file and not in
the dt-database. Personally I do not fill the database with data and
after a fresh install of dt the database is empty, because everything I
need is in the xmp-file.

> Currently, we simply copy the lens entries and mark them as copies

As long as the lens is recognized, there should be no difference for
the user.

The next problem is a solution to get new lenses available in
darktable, easy and fast for the user.

At the moment I am using .local/share/lensfun and use the files from
git. But I think this can be done easier while doing a "normal" system
update.

Again, if there is no official bug report for this topic, I will open
one.

http://lensfun.sourceforge.net/development/
The source code is available from a git repository hosted at
Sourceforge. You can check out the current head revision by

The build system is based on CMake. Enter the Lensfun folder and create

I assume these git-files are here:

But the files there are not from the last days, but months old.

So is this not the development brunch of lensfun?

Well, it was *very* colored, a few letters in yellow, then in blue,
then white or black, a.s.o. I saw this e.g. in the left and right panel,
and when I selected a filmroll.

At the moment everything looks nearly perfect, a little bit too large
fonts, but white letters on dark background in the panels. I have set
180dpi in darktablerc und 144dpi for the system. Because of the
troubles I think I will keep this setting for a while.

In theory I have a little bit less than 140dpi. The monitor reports
itself the resolution is 3840x2160@60Hz (708.48 x 398.52 mm from the
PA328Q manual).

I am guessing, if I set the system fontsize to 144dpi and darktablerc is
144 too, nothing changes, if it is greater than 144dpi fontsize changes.

At moment I am testing 180dpi. A little bit too much, but on the other
side with 600px border it is more or less ok. The goal is to get a 3:2
relation for the picture part of the screen.

Did you enlarge it? Directly from gdrive I can see it, but it is not so
extreme as with dt. Maybe it depends on the graphics driver. I use 
nvidia-381 381.22-0ubuntu0~gpu16.04.2

I tried 288, looks a lot better with colors in the letter, nearly
nothing, but it is too large now.

It is running as a trial at the moment **without** these mentioned
styles, using the dng-files without any changes and saw no important

I couldn't find errors in the output.

$ darktable --noiseprofiles ./presets.json

Nothing happened re noise, maybe because the Pentax KP is not supported
too or I am doing something wrong. I activated noise reduction by
profile only.

I want to keep the xmp files and I know the script
purge_non_existing_images.sh

I have changed e.g. the default values of sharpness, perspective
corrections and a lot of others, which I needed for a filmroll and now
I want to remove all these presets and use the default values.

[darktable-user] Is it possible to configure "alias lenses"

[Аl Воgnеr]

http://lensfun.sourceforge.net/lenslist/ lists eg

smc Pentax-DA 21mm f/3.2 AL Limited

which is an older model, the newer one is

HD PENTAX-DA 21mm F3.2 ED AL Limited

AFAIK the main difference is glass coating, a.s.o, but not the lenses
itself.

So is it possible to create an alias-lensname? It is a lot of work, to
choose the lens manually everytime.

There are a lot of other Pentax lenses with smc vs. HD.

It works now more or less at first sight with the newer lenses. I start
a new thread re

As there are changes when I use it in dt, I didn't remove 'version="2",

Simply, the old version doesn't support my lenses.

After I switched back, the distortion remained until I deleted the lens
calibration, so I "packed" the history and activated the lens
calibration again. Then it was ok.

In the meantime I know, why 0.3.2 didn't work sometimes, I use
different cameras and one was the new Pentax KP, which is not supported
until now. When I assigned a Pentax K3 instead, it worked generally.
Probably not a good idea. I don't understand why the camera is needed
to correct distortion.

> Does anyone know why the repository is still using old lensfun?

Interesting question. I am back to 0.2.8-3pmjdebruijn2~xenial and hope
a new version is coming officially.

I didn't try it until now. Does it make sense to mix it with 0.2.8?

Thanks Romano,

Xenial is my system, so it looks good. The minor problem at the

the website.

Here is 1 sample with 1ISO:
https://www.file-upload.net/download-12516482/pentax.kp.dng.noise.sa_1.8_2.41_1i.dng.html

Can this be used for noise calibration?

Please note:

[EXIF]  0xc62b Baseline Noise  : 1
[MakerNotes]0x0049 Noise Reduction : Off
[MakerNotes]0x0071 High ISO Noise Reduction: Off; Inactive


Default is "High ISO Noise Reduction" on, which is probably used by
everyone. I don't know if this influences the raw-file

I have these samples from 100ISO - 819200ISO in 1/3 steps. (1.4GB)

Please let me know how to go on.

I am asking because https://redmine.darktable.org/issues/11600 is still
unasigned. PEF cannot be loaded with dt, but DNG can, although it shows
something like "choose camera / lens manually"

Ok, so I will produce tons of RAWs

Does it matter if they are in DNG or PEF, or do you want both?

Is indoor preferred? I remember very noisy pictures in winter, which
were not noisy actually. It was warm wet air / fog in certain areas
only. Especially blue at dawn looked very noisy.

Ok, there are so much setting at Pentax cameras, which seem to
influence noise, but should work only with jpeg. Probaby it is best to
turn them off anyway.

Thanks and sorry, I don't still know what you mean and cannot get it

[darktable-user] Automatically removing of vanished and double imported files

[Аl Воgnеr]

Renaming of photos leads to a lot of troubles and I try to find a
workaroud for renamed photos, sometimes with the same name as an older
photo had. This occurs especially with serial photos.

Eg you are taking pictures for a portrait in serial mode and then from
100 edited you keep the and rename then. In this case I change the time
too, so that there is only 1 photo in 1 second and every photo is taken
1 second later in exif-data, while the makernotes are untouched, which
show the actual values.

I am using a bash script to rename photos and the new name has always a
corresponding xmp-file.

Is there a way to remove double imported photos from the database
automatically?

Is it possible to remove vanished photos from the database
automatically?

The xmp-file contains a line with "xmpMM:DerivedFrom=". Could it help
to replace the old filename with the new one?

Roman,

obviously there is a bug, since the pef-file cannot be opened. Download
a pef file from

yourself, please.
