[Digikam-users] Contrast/Gamma settings for DigiKam?

[Risto Saukonpää]

KDE has good color correction settings on monitor settings (right click on 
desktop and screen/monitor > second tab) but normal user dont usually know 
this if they just corrects lighting from own pictures. 

That's why i like suggest that Digikam should get same kind "color card". It 
should tell user basics how to set monitor settings right for viewing/editing 
purpose from KDesktop and from monitor (contrast/brightness etc).

I came up with this when did my friend buy new LCD monitor and throw away her 
old CRT and all her gamma/brightness settings was so hi that screen was white 
with new LCD and he needed to change everything back to normal. Then he asked 
me how should he set the screen and i gave him a "gray-card" (picture from 
web, like KDesktop has). Then he realized that almost all her pictures (just 
few dozen) was edited on too dark monitor and laughed that now he knows why i 
asked from him "why you set these pictures so bright?".

And even new LCD monitors has nice "little" auto-corrections, user still needs 
change screen brightness and contrast.

Second suggestion is that digikam can show luminosity/red/green/blue/alpha 
over picture but it shows all colors as own and there is no option to see all 
colors together as in Picasa. So is there possible way to add this option?
