VIPS is a free image processing system. It is good with large images (images larger than the amount of RAM you have available), with many CPUs (see Benchmarks for examples of SMP scaling, VIPS is also part of the PARSEC suite), for working with colour, for scientific analysis and for general research & development.

VIPS consists of a powerful re-usable library and a graphical user interface. VIPS is very bad at retouching photographs, but very handy for the many other imaging tasks that programs like Photoshop are used for.
