Resolution and Upsizing

[draymorton]

I just mistakenly processed a RAW file at 240 (I meant to process it at 320). Is there a big difference in quality between 240 and 320? Can you upsize to 320 without noticeable image degradation? I've done far too much work on this file to start all over again at 320.

(I assume that you are talking about DPI.) It makes absolutely no difference to a digital image. You can change it to anything you want and long as you don't tell it to RESAMPLE. With Resample, it actually changes the size and, therefore, the pixel dimensions and this does some interpolation/extrapolation which cannot be recovered. It may or may not be noticeable. – Terry
