An image has to go through the lens to the film. To be enlarged it has to go through the film and the enlarger lens and is projected on the paper. At each stage we find different resolving powers. E.g.: The taking lens might be capable of 90 lp/mm, the film of 160 lp/mm, the enlarger lens of 80 lp/mm, etc.) The final resolution would depend on all these factors plus the degree of enlargement. I wish to relate this final resolution to a visual acuity of one minute of arc.
