Canon 500D and a RAW question

[Sven Flossmann-2]

Hi,

I've mainly two questions related to RAW format for which I did not found an answer yet.

1)
digikam uses the embedded JPEG for the Image Viewer. Assuming one performs some changes (e.g. White Balance, ...) in the image editor on RAW images.

• Would the viewer also use this new updated image?
• .. or must the image be converted into another file?
  
• If yes, which resolution / size would the image viewer use?

What I miss is something similar to Adobe Lightroom's: Change something e.g. WhiteBalance and the change is always applied when viewing the image.

2)
I've a Canon 500D. In one mail of this list it was stated that RAW decoding will work fine if 8 Bit color depth is used. However, I always get pink images in the editor. I'm using 1.0.0-beta5 from the Kubuntu9.10 beta repository.

Thanks a lot,
Sven

This depend of libraw included to libkdcraw. use the most recent
version of libkdcraw provided by KDE (from kdegraphics component), and
all will be fine

Hi,

thanks for you answer and your screenshot proofing it would work.

However, I wonder in which version of kdegraphics the Canon 500D would be
supported.

I installed the latest KDE 4.3.3 today and it seems that this version does not
support the 500D.

In the "Supported Camera" dialog I get version 0.5.0 for libkdcraw and version
0.7.2 for libraw.

Do I have to manually install or compile something?

Thanks,
Sven

Here, i works only with trunk code of kdegraphics (KDE 4.4). version is 1.0.0.

Sound like digiKam have not be updated from your packages since you
have updated libkdcraw.

More than on version of this sahred lib can be installed at the same
time on your computer. This is why digiKam still to work

If a new version of libkdcraw is installed, digiKam need to be
recompiled (at least the package). Ask to your distro packager...
