Install RawTherapee 5.7 on Ubuntu and Linux Mint with PPA


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.

News Relevant to Photographers

RawTherapee supports most raw formats, including Pentax and Sony Pixel Shift, Canon Dual-Pixel, and those from Foveon and X-Trans sensors. If you’re wondering whether it supports your camera’s raw format, first download RawTherapee and try for yourself. If a raw format is not supported it will either not open, or the preview in the Editor tab will appear black, white, or have a strong color cast - usually magenta. In that case, read the “Adding Support for New Raw Formats” RawPedia article.

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 a meaningful axis (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!
