In fact my question was more, given a normal LDR image with variation of
intensity clipped between 0 and 1, is it possible to create directly a HDR
image by calculating the intensity value from the clipped one, by using a
function I=f(r,g,b) with I being maximum (and much higher than 1 of course)
for White? As I said, HDR shop accepts to do this but I'm not sure that the
final image really has hot spots (but then I have not tested this
extensively).
In any case, creating HDR maps within POV-Ray would be sweet.
