I'm not sure I understood well your question, but... the quality of the output image is not affected by resolution directly. If you try to enlarge an image (say from 800 to 1024), you will get poorer quality in most cases. Sometimes, downsizing the image could cause a loss of detail and could require a further sharpening. The real important thing is the resolution at which you render the image, not the res at which you save it later. The quality is affected mostly (I'd say a good 75%) by the quality settings you set in Bryce. The rest is hist... ehm, postwork. :) Stefano
