Hi, I am using POV ray for windows, and I am interested in generate images in
12bit, in fact it would be 12 bit per channel, so finally the image would have
36bit(12x3) per sample, 12 per each R G B channel. Is that possible to do?
Thanks!

See section 3.1.2.4 "File Output Options" in the docs.

Quote:

"Most of these formats output 24 bits per pixel with 8 bits for each of 
red, green and blue data. PNG and PPM allow you to optionally specify 
the output bit depth from 5 to 16 bits for each of the red, green, and 
blue colors, giving from 15 to 48 bits of color information per pixel. 
The default output depth for all formats is 8 bits/color (16 million 
possible colors), but this may be changed for PNG and PPM format files 
by setting Bits_Per_Color=n or by specifying +FNn or +FPn, where n is 
the desired bit depth."



I however would also like to know whether Bits_Per_Color affects the 
alpha channel as well.
