PFSTools

PFSTools is a set of command line (and one GUI) programs for reading, writing, manipulating and viewing high-dynamic range (HDR) images and video frames. All programs in the package exchange data using a simple generic file format (pfs) for HDR data. The concept of the pfstools is similar to netpbm package for low-dynamic range images. pfstools are supplemented by pfscalibration and pfstmo for creating HDR images, and for tone-mapping operations, resp.
