Re: saving jpegs in another format?

[Terry <terry@xxxxxxxxxxxxxxxxxxxx>]

The way I understand it each time you open edit and save a jpg file it gets 
compressed over and over which means it looses data, however I have been 
told that if you edit and save a jpg file in PS using PS' lowest compression 
option you will loose no data, but I have never tried it, if it where me and 
I was going to work on any file and save it I would save it out as a tiff 
rather then a jpg. But that's just me.
