reflectance image to albedo values

[ttsesm]

Hi @fqnchina

One technical question in case that you know, once I have the reflectance image, RGB [0-255], how to transform it to the corresponding allbedo values image map, [0-1]?

Is it enough to make it grayscale and then scale the grayscale image to [0-1] range or there is another approach for it.

Thanks.
