exricamtm - performs tone mapping on an OpenEXR image (iCAM)
exricamtm input.exr blur.exr output.exr
Performs the non-linear response compression portion of the iCAM tone
mapping algorithm described in this paper:
G.M. Johnson and M.D. Fairchild. Rendering HDR Images. IS&T/SID 11th
Color Imaging Conference. 36-41 (2003)
The input image should be normalized, and the whitepoint image should
be at the same scale factor as the input image. The output image
should be normalized before viewing.
