Re: What format for save-as on a scanned photo?

If you want to manipulate with a photo package (photoshop) they may

require

a different type format 

Photoshop has no problem w/JPGs. However, what you want to make sure of
(in any editing app) is that you don't open/save/open/save/open/save in
JPG format. Every time you save to JPG the JPG format will throw out a
little more information to compress the image. It doesn't get the idea
that you compressed it once, and it shouldn't do it again. Even if
there's no artifacting in the first image, after a couple of open/save
cycles there will be.

If you start w/a JPG, fine. And if you want to end w/a JPG, again,
fine... But do your intermediate saves in a loss-less format. For
Photoshop I'd go w/PSD (native) but there are others.
