RawTherapee is a cross-platform and open source piece of software that allows users to edit RAW images from digital cameras. It features a 96-bits (floating point) processing engine that provides a non-destructive image editing environment, which enables users to get the most details from their raw images.
Features at a glance
Key features include both traditional and modern demosaicing algorithms, including AMaZE, fast, DCB, AHD, HPHD, EAHD, IGV, VNG4 and LMMSE, advanced color handling, powerful CIE Color Appearance Model 2002 (CIECAM02) module, enhanced tonality and exposure tools, as well as multiple denoising methods.
In addition, it features various tools for enhancing the details in images, such as RL deconvolution, unsharp mask, and contrast by detail levels, supports other image editing programs, such as GIMP, supports dual-monitor setups, batch processing, parallel editing of multiple image files, and different layouts.
Supported cameras and RAW file formats
RawTherapee has been engineered to support a wide range of digital cameras, including models from consecrated manufacturers like Nikon, Canon, Sony and Leica. Additionally, it supports various medium format cameras.
Supported image file formats include all known RAW formats from DSLR cameras, as well as JPEG and PNG files in 8 or 16 bits, and TIFF files in 8, 16 or 32 bits. It can output modified RAW images to JPEG, PNG and TIFF files of 8 or 16 bits.
Under the hood and supported platforms
The project has been written entirely in the C++ programming languages, using the gtkmm language binding and the GTK+ GUI toolkit for the graphical user interface. It officially supports the Linux, Microsoft Windows and Mac OS X operating systems, on both 32-bit and 64-bit architectures.
Summing up, RawTherapee is a very complex and powerful RAW image editor software for the GNU/Linux platform. Actually, it is the only one that hosts so many features under a single roof.
