ART – flexible RAW image processor and local editor

ART, short for A Raw Toolbox, is a RAW image processor derived from RawTherapee. The projects have diverged substantially since the original fork, with ART restructuring both the interface and processing pipeline around its own photographic workflow.

Local editing is a particularly important part of ART. Adjustments can be restricted using drawn, parametric and area masks, while the wider toolset covers exposure, detail, colour, transformations, RAW processing and metadata.

ART can also be extended beyond its built-in capabilities. External programs can be integrated through user commands, custom image handlers can add new input and output formats, and colour workflows can use CTL scripts and ACES CLF LUTs.

This is free and open source software.

Key Features

• Restructured RAW processing pipeline and interface derived from RawTherapee.
• Extensive local editing with drawn, parametric and area masks.
• LibRaw can be used for decoding supported RAW formats.
• ExifTool and Exiv2 integration provides detailed metadata handling and optional XMP sidecar synchronisation.
• Custom image handlers can extend supported input and output formats, including external RAW decoders.
• Supports ACES Common LUT Format files through OpenColorIO.
• Supports CTL scripts using the ACES CTL interpreter for additional colour and image-processing operations.
• Automatic perspective correction adapted from darktable.
• Star ratings and colour labels can be read from and written to XMP sidecars.
• Persistent snapshots are stored inside ART processing profiles, while Inspector mode provides detailed image comparison and inspection.
