When you save an edited file, what is logically the best format to save your work in (not export, just save your changes in a lossless format for the future)?
I've got PSP 8 & X, so would a PSP file be the best choice for saving my work (like a PSD file if I had photoshop).
Is there an accepted standard like PNG or TIF that most photographers stick with?
What are the downsides of PNG and TIF files as opposed to PSP and PSD (other than the fact that there's no layer support)?
Thanks!
