If you're going through a photo album with someone and looking at each picture closely, 450 or more dpi (2250x3150).
If you're putting it in a frame where someone can pick it up and look at it fairly closely, 300 dpi (1500x2100). <== that's usually okay for 95% of the uses by 95% of the population
If you're putting it in a frame on the wall, you could go as low as 150 dpi (750x1050), but preferably 200 (1000x1400). |
Most professional photo printers (Fuji Frontier, Noritsu) top out at 300 or 320 dpi, so saving any more than that (at final print size) may not only waste space, but could actually affect the quality by requiring the printer to downsample your image (better than upsampling though). As mentioned, 300dpi is almost always fine, and even 150dpi (minimum for DPC Prints) is almost always "good enough." |
