I recently read an old Macworld article on scanners. Where I work, we have a scanner with rather limited software with it. In this article, however, I read about contrast enhancement using something called Gamma Correction. I'd like to try it for the Sunraster and TIFF files we have at work. I know the basic principle of remapping the intensities, but I don't know how to compute the curve. What I'd like to know is what's the formula for Gamma Correction? Does anyone have any info they can tell me about it? THanks in advance.
