Hi Folks! Since I often use many of my renderings for multimedia as well as still images, I usually save two versions--one in native Photoshop format (so i can edit the layers later), and one in pict or .pct (I'm on a Mac). Newbies may not be aware that images intended for printing to hard copies need to be saved at 300 dpi or more, while media images are fine at 72 dpi. As such, pct or bmp formats are better for images that I know are going to end up in a PowerPoint presentation or such, while print images are usually saved as tifs. When to use gifs has already been mentioned by others. I'd also like to pass on this information to newbies who might read this thread. No matter what file format you ultimately save to, one should almost never process the only version of an image you have; it's better to experiment with a duplicate. Every semester I have at least 2 or 3 students who learn this lesson the hard way--but they only need to experience it once to appreciate its value. Peter (Dr Zik)
