A raw editor develops the unprocessed data from your camera sensor, and the free options are surprisingly serious. darktable and RawTherapee are both GPLv3 open-source programs for Linux, macOS and Windows, and between them cover most of what paid raw converters do. darktable is built around a non-destructive module stack with a strong library, while RawTherapee gives fine control over demosaicing and color. ART is a RawTherapee fork with a simplified interface, and Ansel is a darktable 4.0 fork aimed at digital artists with a streamlined approach. digiKam includes a raw editing step inside its photo manager, useful if you want one app for organizing and developing. On phones, Snapseed opens raw files in its free app. If you want a polished commercial-style desktop program, Affinity Photo is free for individuals according to the vendor, with a raw development workspace. Choose by interface patience: darktable and RawTherapee are deep and take a weekend to learn, while ART and Ansel trim the options. Check that your camera's raw format is supported, since a new body may need a recent release. The trade-off is power against learning time. Seven options follow.
