Ok, after getting a good dose of negative comments about trying to
make POV-Ray and Photoshop more compatible, in regards to 48bpp
images, I have one burning question in my mind:
What image editor (available for Windows) will open and properly edit
a POV-Ray 48bpp image?
By "properly", I mean it will open the image in 48bpp mode, not 24bpp.
It will be able to perform "curves" and "levels" operations on the
48bpp image. It offers a 24bpp preview on my monitor. It can convert
the 48bpp image to a standard 24bpp file, after I am done tweaking the
curves or levels.
So what software do I use? What software do *you* use?
I'd really like to know.
Thanks,
Glen

Imagemagick, don't know what 'curves stuff' it can do as I mainly use
it for simle things from commandline. Just tried adjust of brightness
and it works, with 48bit PNG input from POV-Ray, the output is also
48bit.
For viewing with Imagemagick you'll need an x-server. I use cygwin/x-
free, but there seem to be pure windows solutions.

Photoshop will, if you use ppm format and tell Photoshop that it's
really a raw image. See Kari's post about this somewhere around here.

Unfortunately, I only have Photoshop 5.0 LE, and not the full package.
I tried Kari's suggestion, but my "LE" version of Photoshop won't open
RAW format images, at least as far as I can tell.
It will open 16 bit per channel images in the PSD and TIFF formats,
but I see no support for any "RAW" formats at all, 16 bit or
otherwise. I also checked for "PPM" and couldn't find any support for
that either. :(
Later,
Glen

In that case, perhaps you can use a recent build of the PBM utilities to
convert POV-generated 16-bit images in PNG or PPM format to TIFF format.
You can find Windows binaries at the URL below, but I note that they are
for version 9.14 rather than the current 9.18 and I'm not sure if they'll
have support for what POV calls a 16-bpp PPM. Can't hurt to try, though.

Thanks for the suggestion. I'll give it a try a bit later.
I don't know about anyone else, but here in West Virginia, I'm having
trouble reaching a lot of internet sites today. I suspect it has
something to do with the terroist activity earlier today, in NYC and
Washington, DC. Suprisingly, I can access the New York Times website
without too much difficulty, but this news group for example, is only
accessable about one in every thirty attempts. Even when I can get
access to this server, it doesn't last for very long. If only the
internet slowdown was the worst problem anyone faced today...
Later,
Glen

I thought that PaintShop Pro might. But I cant even verify that
the files are other than 24 bpp. No mater how I set the option
for pixel depth (+fn5 to +fn16) PSP always shows a 24 bpp/16 million
color report when I ask for image information.
Is it something with POVRay or PSP?

Does Gimp work with 48bpp? It seems to open 48bpp png's okay.

IIRC, the Gimp will open 48bpp, but will only actually use and work in
24bpp +alpha.
For 16bpp, you'd have to look to the 'hollywood' branch

Does the image file size grow when you use more bits per pixel? If so,
that's a quite clear sign that povray is working ok.
