High dynamic range (HDR) imaging has become a powerful tool in
computer graphics, and is being applied to scenarios like
simulation of different film responses, motion blur, and
image-based illumination. The HDR images for these applications
are typically generated by combining the information from multiple
photographs taken at different exposure settings.

Unfortunately, the color calibration of these images has so far
been limited to very simplistic approaches such as a simple white
balance algorithm. More sophisticated methods used for
device-independent color representations are not easily applicable
because they inherently assume a limited dynamic range. In this
paper, we introduce a novel approach for constructing HDR images
directly from low dynamic range images that were calibrated using
an ICC input profile.
