I have a problem when doing grayscale rendering to file – I cannot
find a way to get more than 256 levels of gray, which is not
continuous enough.
If I render to Mono TIFF format, there is only 8 bits of info [0..255]
per pixel giving 256 levels. If I set up a black/gray/white scene
and render to a color (RGB) TIFF or Targa format, there are 24 bits
of info per pixel (8 for Red, 8 for Green, 8 for Blue), but still
only 256 levels of gray, in which the Red/Green/Blue bytes have the
same value: 0/0/0, 1/1/1, 2/2/2, … 255/255/255.
How can I render to file and get more levels of gray? Are there any
settings in 3D Studio or any file formats available that would yield
more than 256 levels of gray – either a mono format with > 8 bits per
pixel, or a color format with > 24 bits per pixel?
