It might help to know what you want to do with the 0-255 RGB values, and why you want to convert the HDR (high dynamic range) into a low dynamic range scale. Greg already pointed out some options in his reply. Is it something that the pcond command might help with? I'm not familiar enough with the code and what the "numbers" are that come out of pcond, but I do know it's intended to allow compression of an image into a lower dynamic range for image representation, even if it would still require further number manipulation to get you 0-255 integers.

I used pvalue -o -h $HDR command but the results are not on the desired range (0-255). Any suggestion is appreciated.
