RawTherapee is a free, cross-platform raw image processing program released as Free Software under GPLv3. It is designed for developing raw files from a broad range of digital cameras and offers a non-destructive, 32-bit floating point processing engine with modern demosaicing algorithms. It is available for Linux, macOS, and Windows and in over 15 languages.
HDRMerge is a free tool that creates raw images with extended dynamic range from exposure-bracketed raw files or a single raw file containing multiple frames. It imports formats supported by LibRaw and outputs DNG 1.4 images with floating point data. It offers a GUI for removing ghosts and a command line interface for batch processing.
GeoEstimation is a tool for estimating the geolocation of photos. Users select an image from a predefined benchmark test set and click a world map to make a guess. Results are shown as a heat map of likely locations and a visualization of contributing photo parts, alongside scene classification probabilities for indoor, nature and urban settings.
PentaxForums Reviews is a review index with in-depth staff reviews and hands-on tests of Pentax cameras, Pentax and third-party lenses, flashes and software. It also hosts user-contributed reviews and specifications for lenses, cameras and accessories.
OpenStego is a free steganography tool written in pure Java. It provides data hiding, which hides data within a cover file such as an image, and beta watermarking, which embeds an invisible signature to detect unauthorized file copying. It supports password-based encryption with AES 128 and AES 256 and a plugin architecture.
Picarta uses AI to predict where a photo was taken, returning estimated GPS coordinates, city, and country with confidence scores. It analyzes visual clues in the image rather than relying on EXIF metadata or embedded GPS tags. The project offers a web app and an API, with on-premise deployment for enterprise clients.
Image forensics tool for checking metadata, compression artifacts, and possible photo manipulation clues.
