Recommend format to use for printing


does it mean we have to switch between 4:3 & 3: 2 depending what size we want to print?

Set the camera to 3:2, then crop as necessary before printing. This way you don't have to fiddle around with switching settings during your shoot. 3:2 prints nicely on 4R (4x6"), 6R (6x9") and S8R (8x12").
