Hi, I want to match output files of my RAW converter with the wonderful jpeg colors the camera produces. I have written a program that calculates lookup table in Lab -space and another which applies this lookup-table conversion to the photos.. it seems to work. Now I'm wondering if it would be possible to somehow generate a custom icc profile knowing a bunch of original rgb + lab values and the corresponding desired rgb + lab values. Which way could I feed this information (look-up table) into argyllcms' tools to generate a profile that maps the colors right? Is this even possible to do.. and does it make sense? Thanks in advance, - Sampo
