I find it ironic that digital cameras can take such noise-free images... that the QuickTime Player cannot display such smoothness smoothly! Well I'm sure it could if a movie had no compression at all, but the resulting filesize makes that unlikely to be useful. What I'm seeing in my digital-based QTVR files is noticeable banding, and not just of sky but of bright lights, etc. Note that the problem does not affect printing or display of the original Photoshop panorama file. I've surveyed a few sources and the top answers seem to be: don't use low number JPEG compression; set the High-Quality bit on; and add noise back into the image, which I've tried but with limited results. Adding noise may be easy to do with sky, since the sky can usually be selected as a unit in Photoshop, but when every light in a room has banding, what to do? And so far, the high-quality bit has not appeared to make any difference in anything. I'm using PhotoJPEG--50 compression, but bumping it up to 75 or 100 made little difference. My monitor is set to millions of colors. Any other ideas?

Corel sells Bryce, promises future Mac versions, from MacNN. I think this is good news, as Corel had previously said they were dropping the Mac version.

Purpose
VRlog provides news, developments and analysis of the virtual reality (VR) world from a nature photographer's perspective. Since I am not connected to or funded by any VR vendor, I intend to objectively appraise what's going on, and the direction VR is headed in. -- erik goetze
