[Bug 307964] New: Not compatible with 5D Mark III

[Vamp898]

https://bugs.kde.org/show_bug.cgi?id=307964

            Bug ID: 307964
          Severity: major
           Version: 2.9.0
          Priority: NOR
          Assignee: [hidden email]
           Summary: Not compatible with 5D Mark III
    Classification: Unclassified
                OS: Linux
          Reporter: [hidden email]
          Hardware: Archlinux Packages
            Status: UNCONFIRMED
         Component: RAW files management
           Product: digikam

The Canon EOS 5D Mark III should be supported since digiKam 2.7.0, but in 2.9.0
it is still _not_ working.

If you open a image it gets a very strong pink color and the image is just
completely unusable.

When i click on Color --> Auto-Correction --> Equalize, that helps on some
photos but not on all and the colors are not always correct.

Sure sure, but i will send you rather this studio shot from dpreview as this
was taken under controlled studio environment with color checker and lot of
stuff

http://movies.dpreview.com.s3.amazonaws.com/canon_eos5dmkiii/5D3_5199.CR2.zip

The embedded JPEG shows fine and correct, but as soon you go to [F4] (the edit
function or you just use showFoto) all is pink

This is how it looks like to me after opening with showFoto

Even libraw 14.6 from the current digikam git seems to not handle this
correctly. I do not have colour management available hence it cannot be the
cause.

dcraw -v -w 5D3_5199.CR2 produces a correct ppm image. dcraw 9.16

So is this a bug in libraw?

As it works with the current RawTherapee, maybe the Color Profile can be taken
from them?

Digikam does not decode RAW on its own. And since dcraw works I'd guess that
libraw is a good candidate.

And indeed, libraw only supports the Mark III only with 0.14.7 and not 0.14.6
which is what digikam ships. Thus you will have to wait until the Help menu >
Components information shows at least 0.14.7 for libraw.

http://www.libraw.org/download#changelog

LibRaw 0.14.7 (27-06-2012)
Imported dcraw 9.15 (1.449):
New cameras supported: Canon 5D Mark III, G1 X, 1D X and Powershot SX200; Nikon
D4,D800/D800E and D3200; Fuji X-S1 and HS30EXR; Casio EX-Z8; Olympus E-M5;
Panasonic GF5; Sony NEX-F3, SLT-A37 and SLT-A57; Samsung NX20 and NX210;
Support for updated Samsung NX200 firmware.
Makefile.msvc: easy additional compiler flag editing.

a few days in the past the raw conversion on my digikam version was switch to
'bilinear' and results where awful with a 7d image. switching back to 'amaze'
restored the good colors. may be you have the same problem

Just saw it in the Screenshot. Current gibt only has 0.14.6 while you already
use 0.15. This just confirms my findings.

--- Comment #10 from Vamp898 <[hidden email]> ---
Im a bit confused

The Homepage of digikam tells for Release 2.7.0

In this release, for a better RAW files processing support, Libraw library have
been imported to libkdcraw with last 0.14.7 release. New cameras are now
supported: Canon 5D Mark III, G1 X, 1D X and Powershot SX200; Nikon
D4,D800/D800E and D3200; Fuji X-S1 and HS30EXR; Casio EX-Z8; Olympus E-M5;
Panasonic GF5; Sony NEX-F3, SLT-A37 and SLT-A57; Samsung NX20 and NX210.

Doesnt that mean that in 2.7.0 it should be included

now i have digiKam 2.9.0, so it should be defently there

here are my version:
libraw 0.14.7
libkdcraw 4.9.2
dcraw 9.16
digikam 2.9.0

Why is the support not there? Is it a wrong information in the News?

Ok if i use the Version Information in the digiKam application itself it shows
the following:

Version of KDcraw: 2.1.0
Version of LibRaw: 0.14.6

5D Mark III is not listet there.

Can anyone tell why digiKam 2.9.0 have libraw 0.14.6 when it should have 0.14.7
since 2.7.0?

libraw is included in libkdcraw, published with KDEGraphics components.
Libkdcraw is managed by digiKam team.

When we updated libkdcraw, it appears in digiKam log. digiKam tarbal include
libkdcraw but pckager prefert to use official release from KDE. This is why you
have an old release of libraw.

Thank you for this! I've downloaded the latest 3.0.0 beta source package from launchpad.net and built it, and it now properly includes the libdcraw stuff and forces you to uninstall the separate dcraw library package etcetera. The point is, it works now, so thanks :)
