OpenEXR

OpenEXR ( http://www.openexr.com ) is a multi-layered 2D image file format which supports floating point data channels.

It is very useful in holding information beyond normal RGBA data, and can accommodate misc render output, such as normals, object ids, Z depth, and High Dynamic Range RGB ;).

See http://www.openexr.com/samples.html for some example usage of OpenEXR from Industrial Light & Magic.

See http://www.lysator.liu.se/~gz/projects/openexr/ for some screenshots of the image codec in action (please add more description here if you like).
