RawTherapee
The RawTherapee Team · An open-source RAW photo processor with advanced demosaicing, color management, selective editing and batch export for photographers.
About
RawTherapee is a cross-platform RAW photo processing application developed by the RawTherapee Team and released under GPL-3.0. It provides detailed control over demosaicing and image development through a GTK-based desktop interface.
Image development
The official project supports RAW files from a broad range of digital cameras, HDR DNG, JPEG, TIFF and PNG images. Selective Editing applies adjustments to individual image regions, while color-management tools, gamut compression, tone mapping, sharpening and lens corrections support a controlled photographic workflow. A file browser and export queue help process collections of photographs. RawPedia supplies documentation for learning the tools and their color-science concepts.
Scope and limitations
RawTherapee is aimed at enthusiasts and photographers who want to understand and control image development. It is not intended as an all-in-one digital asset manager: the official README identifies printing, uploading and asset-management features as workflows that may require separate software. The optional rawtherapee-cli supports command-line processing.
macOS installation
This exact Homebrew entry records 5.13 and downloads the official universal ZIP containing a DMG. The cask requires macOS 26 or later. The upstream 5.13 page describes macOS Tahoe 26.0 or newer on Apple silicon and macOS Monterey 12.0 or newer on Intel; upstream compatibility is not the same as this cask requirement. Unzip the download, open the DMG and place RawTherapee.app in /Applications. The official instructions warn not to rename the app or install it elsewhere.
