Sorry for the stupid question. I'm at a sales conference with work over this weekend and have been volunteered to take a photo of each rep in the lab, these will be printed overnight and framed as a souvenir for them to take home. I figure I can crop in PP (probably with an action) but wondering if I can set up my camera to shoot in a 5x7 ratio?? How would I do this in the menu? Thank you!!!!
