Fotoxx : A photo editing and collection management application

Fotoxx is a photo editing and collection management application. It lets you navigate an image collection using a thumbnail browser, import camera RAW files and edit them with 16-bit color, save edited images as TIFF-8/16, JPEG, or PNG, and edit the whole image or a selected area with adjustable edge blending. It supports multiple undo/redo. Tags, dates, and ratings can be added to images, which can be searched using these criteria as well as file names. Functions include brightness and color adjustments, trim, rescale, rotate, warp, sharpen, blur, noise reduction, red-eye removal, HDR composites, tone-mapping, and panorama.
