Description: High Dynamic Range (HDR) images support a large range in
        luminosity between the lightest and darkest regions of an
        image.  To capture this range, data in HDR images is often
        stored as floating point numbers and in formats that capture
        more data and channels than standard image types.  This package
        supports reading and writing two types of HDR images; PFM
        (Portable Float Map) and OpenEXR images. HDR images can be
        converted to lower dynamic ranges (for viewing) using
        tone-mapping.  A number of tone-mapping algorithms are included
        which are based on Reinhard (2002) "Photographic tone
        reproduction for digital images" <doi:10.1145/566654.566575>.
