## NAME

exricamtm - performs tone mapping on an OpenEXR image (iCAM)

## SYNOPSIS

**exricamtm** input.exr blur.exr output.exr

## DESCRIPTION

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.
