I suppose it would a bit more accurate, atleast in the case of the "Fluorescent" setting, because the values there are based on common types of Fluorescent lighting found and not interpolated. I will send the intermediate values (I noticed that the UFRaw documentation has information on how to do this. I will follow those instructions). Changing this report priority to "minor" based on the discussion. Giridhar -- Y Giridhar Appaji Nag | http://www.appaji.net/
