Thanks for the pointer. I wasn't aware of his work there.
On .raw support not looked much at it because it isn't that deep per
channel bit wise at 12-14 bits usually(1), but might still be useful to
support I guess.
(1) - Not that experienced with .raw myself, but the high dynamic range
is often achieved with bracketed exposures I believe. Been away from the
details of digital cameras for a while though.
With Warp's library though I wonder, if we are looking to make larger
image io / color support changes, whether POV-Ray shouldn't be looking
at all the work under the https://www.aswf.io/# umbrella.
I believe Blender not that long ago moved to those libraries for much
(all?) of their image and color space support. We might for example get
icc png profile support for 'free' - so to speak - using it, where
POV-Ray doesn't support such things today.
If just 32 bit floats / channel max as I expect, it might still be
limited for some of the function related stuff we've been playing with.
In other words, even with it we might want a little more.
There is too netpbm's .pam format - a form of which can be used almost
directly for df3 files.
:-) All sorts of stuff possible.
