pfstools is a set of command line programs (and one GUI program) for reading, writing, manipulating, and viewing high-dynamic range (HDR) images and video frames. All programs in the package exchange data using Unix pipes and a simple generic HDR image format (pfs). It is meant to be similar to the netpbm package for low-dynamic range images. Note that pfs in not just another format for storing HDR images. It is more an attempt to integrate the existing HDR image formats by providing a simple data format that can be used to exchange data between applications.
