Description

Hello,

I have a problem with Darktable and my Panasonic LX100, when trying to open photos with aspect ratio 16:9, 3:2 or 1:1 (but 4:3 works fine).

In the LX100 you can choose the aspect ratio with an on-camera switch so your RAW will have that selected aspect ratio.

I can open and work fine with RAWs in 4:3 mode, but if I try to import and open a RAW in any other aspect ratio (16:9, 1:1 or 3:2) Darktable displays the "Working..." message and consums 100% CPU.

If I kill Dt and reopen it, it will show skulls for the pictures not in 4:3 aspect ratio and the message "Image IMAGE is not available". I can work on the 4:3 ones with no problem.

Running Dt from console give me these messages:

[rawspeed] Camera 'Panasonic' 'DMC-LX100', mode '16:9' not supported, and not allowed to guess. Sorry.
[rawspeed] Camera 'Panasonic' 'DMC-LX100', mode '3:2' not supported, and not allowed to guess. Sorry.
[rawspeed] Camera 'Panasonic' 'DMC-LX100', mode '16:9' not supported, and not allowed to guess. Sorry.

I'm using Darktable 1.6.2 from Ubuntu respositories (version 1.6.2-0pmjdebruijn1~trusty for amd64).

I'll attach sample RAW files with each aspect ratio. I've uploaded them to rawsamples.ch, too.

History

#1 Updated by Roman Lebedev almost 3 years ago

  • Tracker changed from Bug to Camera Support

#2 Updated by Pedro Côrte-Real almost 3 years ago

  • Target version set to Candidate for next minor release

This is now fixed in current git master:

https://github.com/darktable-org/darktable/commit/9aeee061eaf6ce037231cd02abc85a5797c0c89d

It will be included in 1.6.3 whenever we release that. Since the changes are only to cameras.xml you can edit /usr/share/darktable/rawspeed/cameras.xml and add those extra lines (without the leading + signs) and everything should work fine.

#3 Updated by Álvaro Remesal almost 3 years ago

I confirm that the patch is working fine, checked against some other different RAW files with all the aspect ratios works flawlessy.

#4 Updated by Pascal de Bruijn almost 3 years ago

Cherry-picked our 1.6.x maintenance branch:

https://github.com/darktable-org/darktable/commit/5f0dd4461df044c7e0b00799732793fcd9c442e1

So this will be part of our upcoming 1.6.3 release.

#5 Updated by Pascal de Bruijn almost 3 years ago

I just noticed we don't have any white balance presets yet for the LX100 either.

Could you supply us with a single RAW shot per in camera white balance preset (image content doesn't matter).

Pascal, I send you six shots, each one with a WB preset: Auto, Sun/Daylight, Cloudy, Shadow, Incandescent and Flash. I'm not sure if I should post that here, or open a new ticket...
