pfstools package is a set of command line programs for reading, writing and manipulating high-dynamic range (HDR) images and video frames. It includes also Qt and OpenGL HDR image viewers. pfstools can be integrated with GNU Octave or matlab, so that it can serve as a toolbox for reading and writing HDR images.

All programs in the package exchange image data using unix pipes and a simple generic HDR image format – pfs. pfs in not just another format for storing HDR images (and there are already quite a few of them), but is rather an attempt to integrate the existing HDR image formats by providing a simple interface for exchanging data between applications.

pfstools is a base set of tools and more advanced functionality can be found in related packages, such as pfstmo (tone-mapping) or pfscalibration (recovery of camera response curve and merging multi-exposure LDR image). If you are not comfortable with a command line interface or you want to save yourself compilation problems, you may want to check Qtpfsgui, which packages some functionality of pfstmo and pfscalibration in a nice GUI interface.
