luminance pixel selection in Radiance IV

Hi,

I am trying to compare three different images of the same HDRI scene in
Radiance Image Viewer, and I am looking for a way to generate the exact
luminance value pixel reading in each image. Is there a way to accurately
generate such points selection?

Thanks,
Rashida

Hi Rashida.

Radiance has a tool called pvalue. It will print out the pixel values
of an image in the format "x y r g b". You can use the x and y
position to compare values between images.
