John, I am trying to understand your thesis. if I should use a slower and finer grained film with 35mm, I can duplicate these results using a faster, grainier, yet larger formatted film in 6x7? or, an 8x10 produced by a fine grained 35mm negative, can be duplicated by finding a sufficiently inferior film in 6x7? makes sense, and I should be able to find, possibly, a film of such poor quality that my 8x10 negatives will yield contact prints of the same quality.(posted 8325 days ago)the hypothesis is skewed by the process parameters. set your target print size larger and ultimate magnification becomes a large contributor. methinks, the deck is unfairly stacked as you play it.
