I do have an inkling of understanding of what you wrote. Dangerously so! Thank you for your response. My situation right now is trying to communicate with a Windows system from a Mac. I send jpeg images into a Windows system and the guy who gets them is having problems with the pictures being too dark. He is asking me for help. At one time I read an article by Bruce Fraser talking about the translation from a Mac system to Windows and gamma of the two systems.. Can't remember where I found the article and did check Creative Pro. No luck. Now I am being asked for some expertise that I have some knowledge of but trying to explain may be a bit difficult to the person on the receiving end. Am trying to set up a system where the guy on the other end is getting a good/great image. Plus dealing with the press person in the whole mix. I wish I could afford Mr. Tobie's services and his knowledge base is terrific. However, I am on the low end of the pay scale and am just trying to do the best I can. Thanks for the information and I will continue to struggle on. Donna Frank Mares wrote: > D > > Donna, > Colorimeters measure amounts of the three primary colors that specify a > color stimulus.
