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.

Downloads

Source code and binaries of the latest stable version are available at: https://bitbucket.org/agriggio/art/downloads/

Other binaries (nightly builds and/or optimized builds for specific architectures):

  • Optimized Windows binaries: https://drive.google.com/drive/folders/1PiiTzfY1uSD8nV3bzgKDAR4o2aVZUJMS
  • Linux AppImages: https://apprepo.de/appimage/art
  • Packages for openSUSE:
    • Tumbleweed: the package is part of the main repo-oss repository, so it can be easily installed with sudo zypper in ART
    • Leap 15.x: the package resides in the graphics OBS repository, so to install it a few extra steps are needed. First you need to install opi, the OBS package manager, with sudo zypper in opi, and then you can install ART sudo opi ART. Please report any installation/runtime bug here.
  • Packages for ArchLinux and derivates (via AUR): https://clttr.info/art-aur

Features

At a first glance, ART appears very similar to RawTherapee. Compared to the latter, 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 using LibRaw for decoding raw files.

  • Support for ACES CLF LUTs using OpenColorIO.

  • Support for CTL scripts using the ACES CTL interpreter.

  • 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.
