Hi, I've generated a 16bit PNG RGB image from a .pov demo, but need this in
16bit grayscale format? PshopPro reads the image in as 8bit and only allows
editing in 8 bit, anyone know of any good shareware 16 bit editors or a way
to force POV-Ray to generate a grayscale rendering, not color?

Thanks!

hf_gray_16 + png output should do the trick

Thanks, i've tried that now but the resulting PGM file is still only 8 bits
even though i specify +FN16 in the box next to the resolution selection. (I
added hf_gray_16 as a global setting in the .pov file).
Any ideas how to output a 16 bit grayscale?!
Also, is a heigh field true grayscale?

Did you try with PNG files?
