Hi, I wrote a small tool that uses DCRaw to read raw images from digital cameras, and uses LCMS for some basic color management. You can check it out at: http://ufraw.sourceforge.net/
I'm trying to keep the user interface simple, but it is a bit problematic. The problem is that in some cases the raw data has to be manipulated BEFORE applying the color transformation. For example, the profile for the Nikon D70 (it can be downloaded from my site) requires a gamma=0.45 curve, this is a naive gamma curve of pow(x,0.45). Other profiles seem to require a gamma curve which is linear at the beginning. And some profiles are "linear" in the sense, that they can be applied to the raw data directly. Does someone know if the information on the required "preprocessing" is embedded somewhere in the ICC profile? I'm amateur at color management, so any other comments on the way I apply the profiles will be welcome, Udi ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
