Godfrey, We've met and Tanja's recent thread on ages should remind you. I was shooting prints before you were a 'twinkle in your parent's eyes." Fine arts exhibitions I don't know much about, but I spent 10 years with a major printer and publisher and understand commercial printing. And believe me, how a print looks in a book or on a poster depends a great deal on the 4(-5) color press process and the pressmen. Exactly how it looks on a computer screen or an iPad is mainly beyond your control. Generally how it is represented you do have control of, but the fine tuning? You can't even guarantee my screen is calibrated properly.
All this said, projection of slide images and a big lupe on a light table do best for me. Regards, Bob S.
