Re: filmscanners: Re: Scanning problems

Yes, Dean, a very good point that I missed when I first started using 
PS.  I was "blown away" by the quality of JPEGS PS could produce, until 
I realize that I was looking at the exact same uncompressed image with a 
new name in the title bar.

All the conversion does to the image in memory is change the title bar!
As you stated, the only way to see the jpeg is to close the image down 
and load the newly saved one on disk.
