Fotoxx. Én ezt használom.

"Short Overview
Navigate a large image collection using a thumbnail browser, click on an image to view or edit. A rich set of edit and retouch functions is available (see examples below). Import RAW files and edit with deep color. Save revised images as JPEG, BMP, PNG (8/16 bits), or TIFF (8/16). Select an object or area within an image (freehand outline, follow edges, select matching tones, ... ), apply edit functions, copy and paste, resize, blend, warp, etc. without using layers. Edit functions have fast feedback using the full image. Add metadata (tags, geotags, dates, ratings, captions ...) to images. Search images using any metadata and/or folder and file names or partial names. Batch functions are available for renaming, adding metadata, moving, resizing. Fotoxx uses your image files wherever they are and maintains a separate index for fast searching. Fotoxx is standards compliant and can be used with other photo edit programs (no lock-in). Fotoxx is easy to use but unconventional, so please read the user manual (at least a few pages) before jumping in."
Ha jól emlékszem a UFRaw-t is telepíteni kell hozzá.
