I presume you are talking about Photoshop.
Yup, I forgot to make that one clear!
I think that when you save a file
in Photoshop, it compresses a copy of the image and writes it to disk. Thus,
the image on screen does not suffer any loss of information. You can
continue to edit it and save again without penalty. This would continue to
work as long as you did not close the window.
To see the effects of re-compressing a file, you would need to save, close,
open, save again.
What the instructor was clear about was his claim that there is a
difference between Save and Save As...
He was talking about closing the file and reopening and that there is
a difference between the two methods of saving.
He never clarified just what was happening differently. I found his
e-mail address and I will try to get clarification on his thoughts.
This strange concept has never left my mind and I hope your post
eventually leads to clarification for me (and all, in case I
corrupted anyone). I love knowing how things work!
