This is my first attempt at 8x10 portraiture. The lens was a 600mm at about a 1:2 magnification ratio. I shot at F32 and was pleased with the results. Carefull viewers will see that the negative scan had some Newton's Rings problems. I look forward to printing the negative on silver-gelatin paper.
Thanks for the supportive comments! I was worried that even f32 wouldn't be enough to get enough depth of focus, but it worked out ok. On a print her irises are very, very sharp, which doesn't come through in the on-line version. I wish that I knew how to tame fly-a-way hair.
