Re: [darktable-user] New lens --- where do I put the lensfun database entry?

[junkyardsparkle]

The variants apparently don't work, see:

 
https://github.com/lensfun/lensfun/commit/a48bc3afb87d72b48f176890e080a0b094d31b01#diff-50e22dbf0edf411c0bec00e9df83a7ae

But they shouldn't be needed in this case anyway.

Otherwise, not sure why that wouldn't work.

For compact cameras, you also need to add the entry for the camera itself along 
with the lens:


Panasonic

Also, you might have to remove that 'version="2"' parameter to get darktable to

[darktable-user] Greetings and clarifications about styles usage

[Journeyman]

Hello everyone,

new Darktable user here. I've recently started shooting RAW with a great 
Sony RX100 and - as a longtime Linux user - I'm learning a 
bit-more-than-amateurish postprocessing.


I'm referencing the Darktable manual, which is great (thanks for the 
authors efforts), and I've joined the ml to ask a clarification about 
about how styles wotk in Darktable.


I have summarized my doubts in this bullet list:

* I notice that some sort of "default style" is applied automatically 
when a new collection is created (e.g. when I open a folder with 
Darktable). How is this default style defined? Currently it applies 
three transformations: sharpen, orientation and base curve.


* AFAICS in order to create an additional style to be only apllied when 
I want, I can do it from Lighttable: my style should only contains the 
*additional* transformation steps I need besides these defaults that are 
automagically applied.


* How to completely wipe out any transformation style applied to a 
collection/image?
Apparently removing the XMP file is not enough, I need to completely 
remove the collection? As specified here:

http://www.darktable.org/usermanual/ch02s03s02.html.php#d0e2501

Thanks to anyone providing more insight on this.

Darktable really shines in the landscape of FOSS software!

Re: [darktable-user] Canon CR2 colour cast problem with multiple exposures at ISO 50

Yes and no. I believe when the "White balance correction" setting is enabled
on that (and some other?) camera, canon decided to bake the whitebalance
directly into the raw data. And the white balance is still there. So we end up
applying it twice...

Swee, could you please take some other raw image with the same settings
(monochrome, wb corrected), check that it exhibits the same problem, and
upload it to https://raw.pixls.us/ (do read what it should {, not}
contain first please)?
Then there is higher chance of the problem being eventually fixed :)

Your choice, but 2.0.x is old and unsupported :)

Re: [darktable-user] Canon CR2 colour cast problem with multiple exposures at ISO 50

[Swee Oon]

Thanks to all the people who tested out my problem CR2 raw file. It 
seems likely that Canon has written the white balance into the exif for 
such multiple-exposure files in such a way that darktable stumbles when 
reading it. I have had no problems with single-exposure CR2 raw files in 
darktable. Looks like I can put off upgrading my linux OS until later. :-)

The problem is either the wrong white balance being read (is that RAW HDR?),
or wrong black/white levels being read.

I'm using darktable 2.0.7, and it doesn't look like I can get any
other later version because my linux mint 17.3 is based on ubuntu

My Canon 6D does not support raw HDR. The file is just a normal
CR2 raw file, with multiple exposures on it. It's possible that
the multiple "averaged" exposures is screwing up the white balance
data, but then why does the jpeg preview look OK? Strangely
enough, my google drive preview of the file also shows a magenta cast.

Re: [darktable-user] Canon CR2 colour cast problem with multiple exposures at ISO 50

[Koos Pol]

I've run a few checks on openSUSE 42.2. And I made a few funny discoveries:

1. In DT, if I turn the white balance module off, the picture looks very 
much ok.

2. Gwenview shows the picture ok by default.
3. Kolourpaint shows the picture ok by default.
 4. Gimp shows the picture ok by default.

The bottom 3 possible use the same libraries to read the CR2 file. But 
that's just a possibility.


There is definitely a white balance problem. But finding out where it  
is

I shot a photo with 9 multiple exposures (averaged) layered on the same
image using my Canon 6D at ISO 50 (camera's "L" setting). The preview was
fine when I viewed it on the back LCD screen of the camera.

The file imported OK into darkroom. The preview in the lighttable module
looked fine. However, when I go into the darkroom module, there is a strong
magenta cast over the photo. If I exit the darkroom module back into the
lighttable module, the preview image again looked fine. In order for
darktable's darkroom image of the file to look like the lighttable preview,
I had to turn off the white balance module inside the darkroom!

[darktable-user] New lens --- where do I put the lensfun database entry?

[Romano Giannetti]

Hi all,

I have a problem with DT 2.2.4 --- I have bought a new camera, and 
trying to see if I like it --- a Panasonic TZ100. The lens is not in the 
stock lensfun database yet, but I found the entry in the lensfun 
database --- reported below hoping it's correct. Now, I tried to put it 
in a file in ~/.local/share/lensfun/, the adding it directly to the main 
file in /usr/share/lensfun/compact-panasonic.xml, but no matter what I 
do, the lens is not shown in the list of available lenses.


What am I doing wrong?

Same issue with darktable 2.2.4. Preview looks OK until opening the photo
in darkroom. Turning off the white balance module makes it look OK again,
or in white balance module, pushing the tint up all the way to 1.5.
