About

Welcome to the home page of ART, a free, open-source, cross-platform raw image processing program. ART is a derivative of the popular RawTherapee, trading a bit of customization and control over various processing parameters for a simpler and (hopefully) easier to use interface, while still maintaining the power and quality of RawTherapee.

Features

At a first glance, ART appears very similar to RawTherapee. The Getting Started page of RawPedia can be used to get a first idea of how the program works.

Compared to RawTherapee, ART differs in the following main aspects:

• The user interface and the underlying processing pipeline have been significantly restructured, with many tools removed, some new tools added, and several tools rewritten and/or refactored.

• Various new tools for performing local edits have been added, with support for various masking modes (both drawn and parametric).

• A new automatic perspective correction tool (taken from darktable) has been added.

• Better metadata handling (thanks to the exiv2 and exiftool libraries), with (optional) support for reading and writing XMP sidecar files.

• Support for Canon CR3 raw files, thanks to LibRaw (for decoding) and exiftool (for metadata handling). Important: the Canon 1D X Mark III has a new CR3 format, which is not supported yet. If you have the camera and are willing to contribute, please get in touch with the LibRaw folks!

• Star ratings and colour labels can be loaded and stored from/to XMP sidecar files.

• Snapshots are now permanent, saved in the processing profiles.

• Processing profiles have .arp extension instead of .pp3, to avoid conflicts with RawTherapee.

• The "inspector mode" tool of the file browser has been significantly enhanced.

Status

The current version is 1.5.4. It was released on October 3rd 2020.

Documentation

Compilation instruction

See RawPedia. The only difference between compiling RawTherapee and ART is that ART depends also on the exiv2 library.
