First of all, do NOT use bryce to make the jpeg....save as a bmp and use some other program to make it into a jpeg. Make sure gamma correction is turned off. Set antiAliasing to fine art (or higher if you have b5). Do not use the fast preview mode. Go to the skylab and set shadow intensity to about 50...the default 90 is too high for anything but outer space scenes. I've been experimenting with turning on the cast shadows in the cloud cover, and higher ambiance/diffusion in the material lab, with interesting results. Ambiance settings can make or break a scene. 80% diffuse and 20% ambiant is a good start, but not a set rule...different lighting will need different settings. Hope this helps....
