RawTherapee Complete Download and Install Guide

Official Overview

A cross-platform raw image processing program, RawTherapee comprises a subset of image editing operations specifically aimed at non-destructive raw photo post-production and is primarily focused on improving a photographer’s workflow by facilitating the handling of large numbers of images.

Key Features

All the standard features you would expect from a raw developer and much more,
A batch processing queue to make tweaking a photo as fast as possible while leaving the CPU grunt work queued up for later,
Floating point engine – the only raw developer on the market which does all calculations in precise floating point notation so nothing gets rounded off and lost,
SSE optimizations for better performance on modern CPUs,
Color management using the LittleCMS v2 color management system for more precise color handling, providing control over working and output color space,
Support for reading and tone-mapping 16-bit, 24-bit and 32-bit floating-point HDR images in the DNG format,
File browser featuring colored tagging, searching (by text matched to the filename), metadata filtering (by file type, camera model, lens model, photo parameters),
Support for DCP and ICC color profiles, for precise colors or for replicating the “camera look” to match out-of-camera JPEG images,

More Features

A history panel to easily see what changes you made and jump back to a specific point,
A snapshot panel to work with multiple versions of changes to a photo,
A flexible UI where panels and some individual elements can be adapted or hidden,
Easily pan around photos much larger than your screen thanks to pan rate amplification, eliminating the need for numerous and fidgety mouse movements,
Scroll the tool panels using your mouse scroll wheel without worrying about accidentally misadjusting any tools, or hold the Shift key while using the mouse scroll wheel to manipulate the adjuster the cursor is hovering over,
Maximize screen-space by right-clicking on a tool to keep it visible while automatically collapsing the other ones,
A Before|After view to compare your latest change to any previous one,
Support for PP3 processing profiles (sidecar files), whole and partial,

Show various channels in the histogram: red, green, blue, CIELAB luminance, chromaticity and raw,
Color clipping indicators in the preview,

Keyboard shortcuts to speed up work,
Command line support to automate RawTherapee using scripts or call it from other programs,
Support for most cameras,

Preserve IPTC and XMP of pre-tagged files,
