Tony, for us users of Vuescan on a Mac scanning for output to an Epson Printer, would 1.8 be good gamma starting point? Vuescan defaults to 2.2, I'm guessing because most users are on Windows. STEPHENJENNINGS P h o t o g r a p h e r Cambridge, MA [EMAIL PROTECTED] > To be more pr

I used ColorCal's Profiler RGB in manual mode to create a profile that creates printed images that match my monitor as closely as possible, even though my monitor is calibrated for the WEB (6500 degrees). It took a whole day, but I've gotten good results now for a couple months. Anyhow, with this

RE: filmscanners: This Gamma Thing...?

I will take a shot at responding; but there are others on this list who can probably give a much better answer to your question. Generally speaking Gamma represents the midtone setting. In digital cameras it represents the white light setting ( sort of like a light meters 18% gray reference poin
