Kevin,you need to set pvalue -o to get the pixel values from the calibrated HDR image. The pixel luminance is then the weighted average of the RGB channels.
You may use hdrexpo.pl to do the calibration: http://www.jaloxa.eu/resources/hdr/hdrexpo/index.shtml -- simply supply the calibration factor (spot meter reading/HDR value) Cheers Axel _______________________________________________ HDRI mailing list [email protected] http://www.radiance-online.org/mailman/listinfo/hdri
