If you want to do postwork on your render, - do NOT save it as a .jpg. Jpgs is a compressed format, even if you save your image at the highest quality, it will have color losses. BPM is an OK format, - but you'd need to convert it to either post it on the web, or print it. I prefer to save all my images as .TIFFs. It has several advantages; it has no color-loss, and more important, it can save layers. When it comes to .tiff format and print, I'm not so sure, I took a photography to my local walmart in CMYK/tiff format, and could not use their hour print facility. When I asked them, they said that the images had to be rgb/jpg format. But to sum it up, my image archive is no matter of origin (photos, bryce, poser, terragen) made with .tiffs. Before I put an image up on the web, I photoshop it; and use the "save for the web" feature to get the file seize reasonable and to convert it to .jpg. Hope this helps. I have some comments about fileformat on my pages under "how to's". http://www.db-online.com/Britt
