RAWTHERAPEE 5.9 RELEASE NOTES

This is RawTherapee 5.9, released on 2022-11-27.



IN GENERAL

Start by reading the "Getting Started" article on RawPedia:
https://rawpedia.rawtherapee.com/

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!
- All sliders support a fine-tuning mode which you can toggle by pressing the Shift key while dragging a slider.



NEW FEATURES SINCE 5.8

- The Spot Removal tool (Detail tab) was added, for removing dust specks and small objects.
- The Color Appearance & Lighting tool (Advanced tab), formerly known as CIECAM02, now includes CAM16. By taking into account the conditions of the photographed scene and the conditions under which the image is viewed, it allows you to adjust the image in a way which matches human color perception.
- The Local Adjustments tool (Local tab) was added, for performing a wide range of operations on an area of the image determined by its geometry or color.
- The Wavelet Levels tool (Advanced tab) received various improvements.
- The White Balance tool (Color tab) received a new automatic white balance method named "temperature correlation" (the old one was renamed to "RGB grey").
- The Film Negative tool (Color tab) received various improvements including support for non-raw files.
- The Preprocess White Balance tool (Raw tab) was added, allowing you to specify whether channels should be balanced automatically or whether the white balance values recorded by the camera should be used instead.
- A new Perspective Correction tool (Transform tab) was added which includes an automated perspective correction feature.
- The Main Histogram was improved with new modes: waveform, vectorscope and RGB parade.
- Improvements to the Inspect feature (File Browser tab).
- New dual-demosaicing methods in the Demosaicing tool (Raw tab).
- The Haze Removal tool (Detail tab) received a saturation adjuster.
- The RawTherapee theme was improved, including changes to make it easier to see which tools are enabled.
- The Navigator (Editor tab) can now be resized.
- The Resize tool (Transform tab) now allows to resize by the long or short edge.
- The Crop tool (Transform tab) received a "centered square" crop guide, useful when the resulting non-square image will also be used on social media which crop to a square format.

NEWS RELEVANT TO PACKAGE MAINTAINERS

New since 5.8:
- Automated build system moved from Travis CI to GitHub Actions:
  https://github.com/Beep6581/RawTherapee/actions
- libcanberra made optional in CMake via USE_LIBCANBERRA, default ON.

In general:
- To get the source code, either clone from git or use the tarball from https://rawtherapee.com/shared/source/ . Do not use the auto-generated GitHub release tarballs.
- Requires GTK+ version >=3.16, though >=3.22.24 is recommended.
- GTK+ versions 3.24.2 - 3.24.6 have an issue where combobox menu scroll-arrows are missing when the combobox list does not fit vertically on the screen. As a result, users would not be able to scroll in the following comboboxes: Processing Profiles, Film Simulation, and the camera and lens profiles in Profiled Lens Correction.
- RawTherapee 5 requires GCC-4.9 or higher, or Clang.
- Do not use -ffast-math, it will not make RawTherapee faster but will introduce artifacts.
- Use -O3, it will make RawTherapee faster with no known side-effects.
- For stable releases use -DCACHE_NAME_SUFFIX=""
- For development builds and release-candidates use -DCACHE_NAME_SUFFIX="5-dev"
