I don't think the current smart thinking is to save archival stuff as jpegs.
I save just in Photoshop format. Its efficient file size wise and everything
else and you can always set your Photoshop to be backward or not so backward
observant.
At least as a tiff.
And you can do a lossless compression with tiff.
But heck I think the smart people would tell you to save it in Photoshop
format.
Not that that was the question in the first place.


Instead of Tiff save it in TGIF format!
I hope there's a movie I want to go to tonight!

Something with Johnny Depp .. And Gina Lollobrigida!!! Yea that's the
ticket!
