I created an image with a uniform luminance of 1000cd/m^2 using rpict, and displayed it on the display using photoshop as well.
I measured the luminance of the image with a Konica Minolta CS-100A spot luminance meter and found that it was only about 300cd/m^2.
The display is compatible with hdr images and is capable of outputting 1000cd/m^2.
Is there any way to display the luminance of the image created by rpict correctly?
(I have already verified that it is not a problem with the display and photoshop.)
