[Digikam-users] Histogram: RAW vs JPG

[Sven Burmeister]

Hey everybody!

My RAW images seem too yellow to me, i.e. the green is too yellow. I normally 
use a luminosity curve but also tried without it, i.e. increasing the 
brightness etc. with other tools. However as soon as the rest of the picture 
looks ok the green is yellow. For other pictures my luminosity curve works 
perfectly. It's just the green. The same happens when using darktable's 
Panasonic base curve. (I use a Lumix LX3)

I shoot RAW+JPG hence I have two images. WB is set to camera, so the RAW and 
the JPG should have the same. I noticed that the histograms look different, 
e.g. higher curves.

Could somebody please give me a hint how to get rid of the yellowish green if 
everything else seems to fit colourwise?

Yellow green (no luminosity curve applied yet) on the left, normal JPG green 
on the right:

Another thing I noticed in all RAW histograms is that in the middle of the 
third quarter there is always a sudden increase in for green and yellow which 
never occurs in JPGs. Where does this sudden increase come from?

Thanks
