Ralph, If my ultimate large format ambitions were contact printing 5 x 7 and larger, along with exploring platinum/palladium would you start at 4 x 5? I now know this size would be ideal for my processor and probably make a lot of sense to progress into the LF realm. However, I have no desire to simply produce 4 x 5 negatives for practice or to even produce large size gallery prints. Is 4 x 5 really the avenue to enter large format if future contact printing is the goal, or is it a convenient way to have my Jobo processor drive my entry into this medium? I value your feedback on this topic and I certainly see the merit in 4 x 5 but I'm still on the fence?
