From the developer:
Light Compressor lets you easily combine multiple exposures into striking HDR images. Simply load up any number of images and Light Compressor will combine (and align if necessary) the images for you allowing you to tweak the curves, tone mapping, and saturation.
A must-have companion for anyone who shoots bracketed images, or people wanting to give individual images that HDR look through the use of tone mapping.
