The accepted viewing distance for a print is 1.5 times the diagonal. This allows the human eye to see the entire image without "scanning". If we apply this to an 10x8 the viewing distance is just under 13". To view a 60"x40" from the same neg we should stand at around 80". In both cases our eye will see the same amount of detail and the same amount of grain. DOF or even apparent DOF does not change. If we view a large print from a lesser distance, we are NOT looking at the picture, we are looking at other less important or irrelevant stuff . Top pictures are not known for their DOF or their lack of grain or the amount of magnification the negative underwent. The PICTURE is of utmost importance. I am sure that some of you learned gentlemen will correct me if I am wrong.
