Bracketeer is a front-end GUI for Enfuse. Enfuse is a command-line opensource utility which uses multiple exposures of a scene (bracketed exposures) and merges them together to form a uniformly lit scene. It is similar to tonemapping with an HDR image except that no HDR image is ever created, and there are no halos. It works with any kind of bracketed image set, not just panoramic equirectangular images. Bracketeer can even auto-align hand-held shots! The results are almost always much better than anything that can be achieved with Photoshop's HDR Tone Mapping.
