I'm not sure that there is a direct correlation. I made my comments based on years of mini lab experience. Most minilabs work on percentage. A button is usually about 8% change, but this is based on the exposure the machine decides is correct. So on a very over exposed negative one button is going to add more CC's of color then a correctly exposed neg with the same 1 button. It gets more confusing when you consider that 1 button on the over exposed neg may not show as much change on the print (or monitor) as the 1 button on the normal neg. I think Photoshop is more linear. Butch Each man had only one genuine vocation - to find the way to himself. Hermann Hesse (Demian)
