I do most of my original renders at 3000 x whatever (3000 being whatever the widest is be it length or width) 100 dpi. I just had to retouch slightly my Dragon! image to get it to even out because up until a short while ago I only did renders at screen res (72 dpi) and slightly smaller. The larger size helps with the post work too. Anyway, I had to clone some of the stars on either side to get it to come out to 30" wide but it still looks pretty awesome. I also upped the dpi on a resize in Photoshop to 300. Didn't seem to kill the quality at all. I'll let you know when I get the print. :D Anyway, as far as screen size goes...it's pretty damn big. At 100 dpi that's a 1:1 ratio. It's as big on screen as real life...at 300 it's a 3:1 ratio. It's 3X bigger on screen than in real life. Like I said...pretty damn big. You can't "enlarge" a jpeg generally that will degrade the quality. When you render, save it as a tif image, tifs are "lossless" file formats, Jpegs and Gifs are considered "lossy" meaning when you save them, they tend to lose data, thereby degrading the quality with each subsequent re-save. I try to keep my image in .psd format until I'm ready to save the absolute final image, usually reduced to put up on R'osity. I save the final psd, then flatten the image and save it as a jpeg, close the original psd without saving the flattend image so you will always have your large layered original to go back to. Then I reduce the jpeg to a good display size for here and save it again. Sorry if that got too in depth or wasn't really the information you were looking for... LOL I tend to babble :D
