ImageStack is a stack language for manipulating images. It is appropriate for use on the command line and in scripts. Internally, all data is stored as 32 bit floating point, so ImageStack is good for high dynamic range data. ImageStack is also useful for low dynamic range data, which it treats as values between 0 and 1.

ImageStack supports a wide variety of image processing operations, including recent techniques from the computational photography literature. Indeed, its key design goal is to make it easy to implement and experiment with new image processing techniques, in an adequately compute- and memory-efficient manner.
