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>.
