We're proud to announce the new feature release of darktable, 5.4.0!

The github release is here: https://github.com/darktable-org/darktable/releases/tag/release-5.4.0.

To build from source, do not use the autogenerated tarball provided by GitHub on the release page, download our tar.xz file instead. If you're just building for yourself without creating a package for some distribution, then using source code cloning in git is an even more convenient way.

The checksums are:

$ sha256sum darktable-5.4.0.tar.xz
??? darktable-5.4.0.tar.xz

$ sha256sum darktable-5.4.0-x86_64.dmg
??? darktable-5.4.0-x86_64.dmg

$ sha256sum darktable-5.4.0-arm64.dmg
??? darktable-5.4.0-arm64.dmg

$ sha256sum darktable-5.4.0-arm64-13.5.dmg
??? darktable-5.4.0-arm64-13.5.dmg

$ sha256sum darktable-5.4.0-win64.exe
??? darktable-5.4.0-win64.exe

$ sha256sum darktable-4.8.1-x86_64.AppImage
???  darktable-5.4.0-x86_64.AppImage

When updating from the stable 5.0 series, please bear in mind that your edits will be preserved during this process, but the new library and configuration will no longer be usable with 5.0.

You are strongly advised to take a backup first.

Important note: to make sure that darktable can keep on supporting the raw file format for your camera, please read this post on how/what raw samples you can contribute to ensure that we have the full raw sample set for your camera under CC0 license!

Since darktable 5.2:

  • ??? commits to darktable+rawspeed
  • ??? pull requests handled
  • ??? issues closed

Please note that the darktable documentation is not currently complete for release 5.4 and contributions are greatly appreciated. Please see the project documentation for more information on how to contribute.

The Big Ones

The following is a summary of the main features added to darktable 5.4. Please see the user manual for more details of the individual changes (where available).

  • A new section Capture Sharpening is added into the demosaic module. The capture sharpening tries to recover details lost due to in-camera blurring, which can be caused by diffraction, the anti-aliasing filter or other sources of Gaussian-type blur.

  • Added a new tone mapper implementation based on Blender's AgX display transform. The new module's color output is similar to that of Sigmoid, but the provided set of controls is more extensive. It allows for setting exposure white and black points explicitly, similar to Filmic RGB. The implementation includes a user-adjustable pivot point for the tone curve, with the default set at 18% mid-gray. Contrast around this pivot is adjustable. Controls are provided to create a section of constant contrast, and independent sliders are available to control the contrast in shadows and highlights (the "toe" and "shoulder" of the curve). The resulting output is characterized by a gradual color desaturation in highlights, similar to film, and a natural-looking color representation in mid-tones and highlights.

UI/UX Improvements

  • Show a busy cursor when changing views. This provides immediate feedback when, for example, double-clicking an image in the lighttable instead of simply freezing the UI until the darkroom has finished opening.

  • Added the standard "Window" menu to the application menu bar on macOS.

  • In the navigation windows, the zoom is now better behaving. After a free zoom over the darkroom, using the scroll over the zoom level indicator of the navigation window, the selected zoom will be the closest match (above or below depending on the scroll direction). This is better as previous behavior where the zoom level was always set to "small".

Performance Improvements

  • Tune performance for the Lut3D module (5% to 20% speed-up).

Other Changes

  • Allow using Shift modifier to select only the feather points on blend masks. This is sometime needed when the path point and the feather point are too close to each others.

  • Hierarchical presets are now supported for utility modules as well as processing modules.

  • Dual demosaicing now works also in tiling mode for possibly better OpenCL performance and smaller CPU memory pressure.

  • Added automatic compensation of camera's hidden underexposure for Nikon HLG tone mode and Fujifilm DR200/DR400 modes.

Bug Fixes

  • Fixed some issues with the hierarchical styles handling in the styles module.

  • Fixed moving additional extra audio or text sidecar files when an image is moved.

  • Fixed module based collection restoring. Leaving darktable with a module based collection was after restart displaying an empty lighttable.

Lua

API Version

  • API version is now 9.5.0

New Features

  • ???

Bug Fixes

  • Fixed a bug where changing the image scaling in the export module influences the result of a running export job.

  • Make sure we always fill the complete main darkroom canvas while zooming at large scales.

Add action support for Lua

Other Lua changes

  • N/A

Notes

  • When exporting to AVIF, EXR, JPEG XL, or XCF, selecting specific metadata (e.g. geo-tag or creator) is not currently possible. For AVIF, EXR, JPEG XL, and XCF formats, darktable will not include any metadata fields unless the user selects all of the checkboxes in the export module's preference options.

  • Starting with release 5.4, macOS versions older than 14.0 are not supported.
