[Digikam-users] RAW and white balance issue (newby)

[Francisco Lorés Ara]

Hi Francesco,

I have also an EOS450D and use digiKam 0.10.0 from openSuSE 11.1 RPM repo. I 
did the same as you with filemon to discover which camera profile is used by 
Canon software. I configured my camera to use AdobeRGB color space instead of 
sRGB.

I found that using la.icc (Landscape AdobeRGB) or sa.icc (Standard AdobeRGB) 
gives quite good results. These profiles can be found (at least in my Window$ 
box) under the folder

C:\Program Files\Canon\Digital Photo Professional\icc

There are in fact a pair of ICC profiles, one for sRGB color space and one for 
AdobeRGB color space, for each picture style available

Faithful: fs.icc, fa.icc
Landscape: ls.icc, la.icc
Neutral: ns.icc, na.icc
Standard: ss.icc, sa.icc
Portrait: ps.icc, pa.icc

See the attached screen captures of my color management and RAW decoding 
settings. I checked also "Use Raw Import Tool to handle Raw image" on the Edit 
settings tab.

It is important to try to "calibrate" the monitor's black point, white point, 
and gamma, at least "eyeball" if you (like me) don't have a spectrophotometer. 
I used for this purpose the excellent tutorials and charts written by Norman 
Koren at

Hope all this helps :-)

Best regards
Francisco
