10 x 12 = 6 plus one wet plate holder

7 x 17 = 3

16 x 20 = 2

20 x 24 = 2 plus one wet plate holder

Of course the wet plate in coat one and shoot. I carry a changing tent for the film holders. I rarely shoot more than four shots in a day for the 16 x 20 (which is a reducing back for the 20 x 24) or the 20 x 24.
