RawTherapee 4.2 is out, and if you're not using it in 5 minutes then you're not one of the cool kids.

Read the full article...
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*: http://rawtherapee.com/shared/source/rawtherapee-4.2.tar.xz [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!
