Just to be sure, different types of papers have different resolutions. Generally speaking, highly textured paper will print far less detail then glossy of the same size.
Very true. What I wanted to make clear is to keep everything the same except scaling the lens and then compensating by making prints of the same size and you'll see that aberrations scale with the lens.
The real differences in formats fundamentally occur with the film (scaling of the grain with enlargements).
