What is the relationship between print size and subject matter? This is a large format question because I am thinking of contact prints. Does anyone carry an 8x 10 camera, for example, and use a 5x7 reducing back for a shot because a final 5 x7 print feels right for the subject matter? (I am not talking about using a red ucing back to save money or use a particular film.) Is a bigger negative/print a lways better? Can a large format negative ever be too large?
