ExposureManager, et al, are really only made for events. You'd lose a lot of money using them for portrait proofing.

I didn't know you had those as standard sizes. Are you saying you are forced to crop all your images because in your area your "standard" sizes don't match your uncropped image?

In my country you can get 4x6, 5x7, 6x8, 6x9, 8x10, 8x12, 10x12 and 10x15 inches from any lab in a matter of minutes, and bigger ones after about a week or so. I would call A2 standard if I had to, as it's the commonest portrait size for me. Obviously I seldom have any need for "oddball" sizes which don't match my photographs, unless I want to crop them that way. In that case, I can trim them accordingly or order them to the nearest paper size, such as 16x20. Frames are whatever size I order, which I am sure is the same for you.
