Hi Folks! Interesting idea, Darth. Another consideration might be which version of a particular program you have. Newer versions often don't behave the same way as their predecessors. I have both v3.05 and 5.0 of Photoshop (Mac) and their treatment of layering and color management is very different. I often have to take older image files rendered in Bryce and processed as pict or tiff files in v3.05 and tweak their colors or other settings in v5.0 before I can use them in Poser4. A whole nother set of issues emerges when I save them as jpegs for web uploads. And of course, there's the file size thing .... Still, it's a concept worth exploring more deeply. Peter (Dr Zik)
