16 bits per channel rendering
Posted: Sat Feb 12, 2005 2:20 am
Hello, all!
I've been nagging about this for awhile, and since I'm recently returning to Blender to help out with some work I thought I'd bring it up again.
I'm doing some video editing that involves highly accurate color correction: namely editing in 16 bits per channel RGB. When dealing with large images and subtle coloration changes you can quickly get into banding issues when you're stuck at 8 bits per channel (aka 32 bit RGBA), but the additional headroom afforded by 16 bits per channel (aka 64 bit RGBA) eliminates these problems for larger renders.
I believe I recall seeing that the internal math is done either in floating point space or 16 bit space, and so I would love to see a selector for "8 bit" or "16 bit" color!
Many thanks for considering,
