CIEXYZ value of hdri

Hello everyone
Is there a way to get CIEXYZ value (x,y) of an HDR image under different illuminant directly ?
Thanks!

Hi Farzaneh,

You need to be a little more specific with your question.

If you use the "-c xyz" option to raw2hdr, and output to a ".hdr" file, it will write out XYZE pixel values. I have not found this to be terribly accurate, however.

Also, this will not "discount the illuminant" if you have your camera's white balance fixed to daylight, as you should.
