How do I told POV-Ray to output 16 bits grayscale PNG images ?
(not red-green 2*8 bits).
Gforge aside, which software is capable of working with these
files ?

+fn16 (in connection with hf_gray_16)

AFAIK not many. Neither Leveller nor Wilbur can handle them. Most
graphic programs and viewers can read them as 8 bit greyscale.

POV itself, of course.

Actually, I've gotten the impression that the current Hollywood GIMP
uses a 16-bit floating point format. It sounds like GIMP 2.0 (long way
off) will have full 16-bit support.

http://film.gimp.org/gimp.pdf says
"GEGL abstracts the color model and color depth (8-bit, 16-bit,
float)..." and "[GIL] has been implemented for the case of ... and data
types (float, 8bit, 16bit)"
More relevant is:
"The film version of GIMP supports both 16-bit and floating point
channel data"

Found some more from ftp://ftp.gimp.org/pub/users/rayl/gimp.README
"- comes up in 16 bit by default. 16 bit is well tested, 8 bit is
probably fine. no guarantees about floating point yet, that's
still under development"

OK, I'm going from what I'd heard some of the GIMP developers saying at
SIGGRAPH last year. Maybe the 16-bit (integer) is further along than
I'd realized.
