I'd like to post some pics taken with my Super Takumar 135mm f/3.5 lens so I can get a sense of the quality of its performanace from other users. Having only 4x6 prints to scan, save, and upload, I'm wondering if there's some way to get them on PF at a larger size - 8x12, say - so the lens can be fairly evaluated. I know I could scan at 72 psi and just blow them up, but that would present quite a lousy view of the lens' ability. I thought of scanning the prints at a higher resolution. I can get a large, sharp display of them in Photoshop that way, but they would end up being displayed at 72 psi (I believe) and showing at 4x6 here anyway - not much of a view. No resolution pro here, so any suggestions much appreciated.
