ART vs ON1 Photo RAW

ART is a free, open-source RAW image processor for Linux, macOS and Windows. Derived from RawTherapee, it aims for a simpler interface while retaining processing power and quality. Its editing capabilities include layers, batch editing and local adjustments using drawn or parametric masks. It handles metadata and can optionally read and write XMP sidecar files. A plugin system supports custom input and output formats, including true HDR output. For color work, ART supports ACES CLF LUTs through OpenColorIO and CTL scripts through the ACES CTL interpreter. It also includes automatic perspective correction adapted from darktable. User commands can connect external programs; documented AI masking and denoising workflows rely on separate open-source tools, and the project says full AI-tool integration is unlikely in the foreseeable future. ART is licensed under GPL version 3 and comes without a warranty. Stable binaries are linked from GitHub releases, with additional builds listed for Windows, openSUSE, Arch Linux and notarized macOS. Questions and bug reports can be directed to its GitHub issue tracker or discussion board.

ON1 Photo RAW is paid desktop software for photographers who want RAW processing, editing, organization and export in one application. It supports batch editing, layers, masking, AI retouching and cloud sync, and browses files where they are stored while providing tags, albums, stacking and AI keywording. Built-in AI tools include NoNoise AI, Resize AI, Generative Erase, Sky Swap AI, Restore AI and Brilliance AI. Super Select AI, subject and background masks and AI depth masks target specific areas. Optional connections are listed for Photoshop CC, Photoshop Elements, Lightroom Classic, Apple Photos and Affinity Photo; MAX adds Adobe Photoshop and Lightroom plugins. Restore AI uses cloud processing, and ON1 says submitted photos are not used to train models. The standard edition installs on two computers, MAX on three, and subscriptions on up to five, depending on plan. A 30-day trial is available, with no free plan.
