Hello folks, Would you like to explain how the OpenEXR format should be used in color management pipeline ?
In my opinion, the EXR support FP16/32 format, we can record linear light in real world with nearly unlimited dynamic range, take an example, in Paul Debevec's HDRI tutorial, the sun is brighter than the perfect diffuser nearly 46000 times, so if we record the reference white with CIE XYZ, the part about the sun on image should be 46000 greater than the white part, a ( thick white paper or silk ) ? We can apply this image (also maybe RGBE format) to HDR illumination in generating CG content (gather in RSL?). But because even the high-end digital camera such as Panavision Genesis can't record scene in 46000:1 such a huge dynamics range, we still work with the limited dynamics range in CG production. Am I right ? Thanks very much and sorry for my poor English. _______________________________________________ Openexr-user mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/openexr-user
