Actually I was just editing a tif on my PC in both paint shop pro and photoshop (I switch back and forth). I always thought tif was a natice PC format and was suprised to find it available on the Mac as well. All of the image editors I use on both my PC and Mac save jpeg's in terms of percentage of loss or percentage of non-loss rather than a flat 1-10 scale. What are you using to image edit? Even at 0% loss/100% image the jpg's don't look as good as the tif's, bmp's, psd's (photoshop), cpt's (corel), png's (fireworks) or psp's (paint shop pro). I don't have painter on either machine and corel's only on my PC (is there even a mac version?). I've yet to look at a p3d file in a flat display to compare it but I would assume the same. the jpg routine is a lossy one and there is always some level of degredation. By the way the tif I was working on was saved on my MAC in photoshop using the MAC setting for a tif and then opened on PC. Saved in photoshop and later opened on the PC in both paint shop pro and photoshop. JPG's compress well. I use them in my webwork when I need small files with more than the 216 websafe colors. But I never make a statement of quality or color purity behind them. They're just too lossy for it.

Truth has no value without backing by unfounded belief.
