Hi Tokiop,

And thanks for your ideas.
As you mentioned, this method would need to use HDR images to give accurate results.
Here, you map a rainbow gradient to the image's black-White gradient which is far from representing the full dynamic range.

Anyone aware of a tool which could do the same on a HDR file ?
NL ? This "false color rendering to show light distribution" ... would'n it be nice to provide this tool to help users improve their renders ?

No one's there.

Hello Osuire,

sorry no more ideas, but for the waiting i think clay render + fixed value emitters for calibration can give a not so bad approximation. Hdr could give extra information but i'm not sure it is necessary.

Good luck with your tests and let us know if you find interesting tools !

This great little software will allow you to create false color images representing the luminance map of a HDR image.



Many thanks to Axel Jacobs from http://luminance.londonmet.ac.uk/webhdr/index.shtml for guiding me.
