Default HDRtist Free Mac OS X HDR software

HDRtist is Free Mac OS X HDR software. I have not tested it, I cannot vouch for it, but the samples look nice.

HDR stands for "High Dynamic Range". It's a technique of layering (or "stacking") digital photos to increase the range of tones in a photo. The idea is, you take three (or more) exposures of the same scene: one under-exposed, one "correctly" exposed, and one over-exposed, then digitally "stack" them together. The under-exposed layer brings out detail in highlights (which are often blown-out in "correct" exposures; the over-exposed layer contributes detail in the shadow areas; and of course, the "correct" exposure contributes most of the mid-tones. The merged result is a photo that has a wider range of tones, running from the highlights through the shadows. The results can be breathtakingly realistic, if everything else (focus, depth of field, colour) is right, too.

Photoshop has an HDR function (File/Automate/Merge to HDR...), so if you've already paid the big bucks for PS, this freeware product wouldn't be such a big deal, unless the interface or other features are any better.
