darktable

darktable is a photography workflow application and non-destructive raw developer. It acts as a virtual lighttable and darkroom, keeping your digital negatives in a database so you can browse, develop, enhance, and export images without altering the originals.

The lighttable view lets you zoom through and rate your collection, while the darkroom gives you the tools to fine-tune each shot. Optional AI-powered modules add object masks, denoise, and upscale - off by default, and able to run on the CPU or use GPU acceleration when you turn them on.

Finished images can be exported to local folders or remote storage. darktable runs on Windows, macOS, and Linux, and is free under the GPL-3.0-or-later license.
