RawTherapee is a very powerful cross-platform raw image processing program for Windows / Linux / Mac OS X

Windows and OS X users can grab RawTherapee 4.2 builds from our download page. The OS X 10.7 version works on 10.8 and 10.9 too. As none of the builders use 10.10, you could be the first to help get RawTherapee running on that operating system - discuss here. The Linux build of RawTherapee-4.2 should be available from your package manager - if it is not, file a request for it on your distribution's bug tracker (search the internet for "distro bug tracker" where distro is the name of your distribution).

Source code*: [7MB]
* If you're a photographer/user, then get a build from our download page. You cannot run the source code.

Be sure to read RawPedia to understand how each tool works to make the most of it.

In order to use RawTherapee efficiently you should know that:

    You can scroll all panels using the mouse scroll-wheel.
    You can right-click on a tool's name to automatically expand it while collapsing all others.
    To change slider values or drop-down list items with the mouse scroll-wheel, hold the Shift key. This is so that you can safely scroll the panels without accidentally changing a slider or other tool setting.
    All curves support the Shift and Ctrl keys while dragging a point. Shift+drag makes the point snap to meaningful axes (top, bottom, diagonal, other), while Ctrl+drag makes your mouse movement super-fine for precise point positioning.
    There are many keyboard shortcuts which make working with RawTherapee much faster and give you greater control, make sure you familiarize yourself with them on RawPedia's Keyboard Shortcuts page!

New features
since 4.1

    RawTherapee-4.2 includes many speed, precision, stability and memory usage optimizations. As such, users of 32-bit operating systems may now find that they can enjoy more stability while using the most memory intensive tools. Of course users of 64-bit systems benefit from this as well. Refer to the full changelog for more information.
    Powerful color toning tool.
    Curve control of luminance noise reduction.
    Median filter in the noise reduction tool.
    Film simulation tool using Hald CLUT pattern files.
    Command-line option to define bit depth of output TIFF/PNG file.
    Multiple improvements to dead/hot pixel handling, see RawPedia.
    Filename of currently opened image shown in the titlebar.
    Clip control for the flat-field correction tool.
    Demosaic method "Mono" for monochrome cameras, and "None" for no demosaicing.
    Copy/paste processing profile keyboard shortcuts for right-handed users using Ctrl/Shift-Insert.
    Update to dcraw 9.22 1.467

High Image Quality

    96-bit (floating point) processing engine.
    Non-destructive editing.
    Get the most details and least artifacts from your raw photos thanks to modern and traditional demosaicing algorithms: AMaZE, DCB, AHD, EAHD, HPHD, IGV, LMMSE, VNG4, Mono and Fast.
    Advanced color handling from white balance to HSV (Hue-Saturation-Value) curves, color toning and color management.
    Powerful CIE Color Appearance Model 2002 (CIECAM02) module.
    Enhanced exposure and tonality tools: tone and Lab curves, highlights and shadows tools, tone mapping (HDR-like effect), etc.
    Multiple denoising methods: luminance, chrominance (both rewritten in 2012), impulse (for salt and pepper noise) noise reduction.
    Several tools to enhance details: unsharp mask, RL deconvolution, contrast by detail levels.


    Multi-threaded algorithms for high performance (RawTherapee can utilize modern processor features, like SSE).
    Quick thumbnails load lightning fast and are replaced later with live thumbnails.
    Batch processing: convert all the developed images at once without loading the processor while you work.
    Copy/paste editing parameters from one file to many other. Partially copying and/or pasting is also possible.
    Basic tools immediately at your hands.
    Parallel editing of multiple images in separate editor tabs, and/or all at once from the file browser.
    An optional secondary display can be used.


    Wide variety of supported cameras: almost all DSLRs and even some medium format bodies are supported.
    Can load most raw files including 16-, 24- and 32-bit raw HDR DNG images, as well as standard JPEG, PNG (8- and 16-bit) and TIFF (8-, 16- and 32-bit logluv) images.
    Can save JPEG, PNG (8- and 16-bit) and TIFF (8- and 16-bit) images.
    Advanced control over the algorithms with many fine-tuning parameters and curves.
    Can send to GIMP or the editing tool of your choice in one click (16-bit TIFF file).
    Command line usage besides the normal graphical interface.
    Various layouts: multiple tabs, single tab with filmstrip, vertical tab with filmstrip, dual monitor.

Freedom for Free

    RawTherapee is free and open source software, meaning you can use it free of charge, wherever you like on whatever hardware you like, as long as you abide by the copyleft GPLv3 license. Download the source code, modify it, feel free to do what comes to mind. We believe in open software.
    It is cross-platform: Linux, Mac, or Windows, be it 32-bit or 64-bit - you pick, we provide.
    International: it is available in 25 languages!
