I have ordered a couple of 8x12 prints from Nations Photo Lab and they are to be delivered on Friday. I want to make sure they are going to look OK before I offer those up. Assuming they turn out fine you can go to that web site and decide what size, paper, or other options you want. I will assume these can be enlarged to 12x18 with decent quality. Any sizes that aren't multiples of 2x3 will require cropping, so you'll need to specify how you want that done.

I just got the 8x12 prints I had made today. They look quite nice and are well worth framing and hanging on the wall. As I mentioned previously you could probably get away with enlarging them as big as 12x18, but any larger than that and the resolution of the 35mm format reaches its limits at least for close viewing.
