We're proud to announce the new feature release of darktable, 5.0.0!

The github release is here: https://github.com/darktable-org/darktable/releases/tag/release-5.0.0.

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-5.0.0.tar.xz
??? darktable-5.0.0.tar.xz
$ sha256sum darktable-5.0.0-x86_64.dmg
??? darktable-5.0.0-x86_64.dmg
$ sha256sum darktable-5.0.0-arm64.dmg
??? darktable-5.0.0-arm64.dmg
$ sha256sum darktable-5.0.0-win64.exe
??? darktable-5.0.0-win64.exe

When updating from the stable 4.8 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 4.8.

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!

Please note that the darktable documentation is not currently complete for release 5.0 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 5.0. Please see the user manual for more details of the individual changes (where available).

  • This development cycle has included a large number of changes which improve the user experience, as detailed in the next section.

  • ???

UI/UX Improvements

  • Added camera-specific styles for more than 500 camera models to more closely approximate the out-of-camera JPEG rendition. These styles only affect contrast, brightness, and saturation and do not attempt to match sharpening, denoising, or hue shifts. Also added a Lua script to auto-apply the appropriate style on import and manually apply styles to a collection of previously-imported images.

  • The user interface now gives feedback while processing bulk image operations such as rating, tagging, applying styles, and edit history management (and undoing those operations), rather than silently freezing until the operation completes. While the operation is in progress, darktable will now show either a busy cursor (such as a stopwatch or spinner) or a progress bar with option to cancel the remainder of the operation.

  • Added a high-contrast theme with bright white text on a dark gray background.

  • Enhanced tooltips for utility module headers to provide more information about the module.

  • Added more new-user hints on an empty lighttable.

  • Added two new error placeholder images to distinguish between missing, unsupported, and corrupted images. When attempting to edit such an image, an appropriate, more specific error message is displayed.

  • When selecting a style in the export module, hovering on the style name in the popup menu displays a thumbnail previewing the effect of appending the style to the active image's edit (first selected image in lighttable, center-view image in darkroom).

  • Allow for selecting the utility modules to be displayed on the panels in the different views.

    • Right-click on the empty panel area below the modules to get a menu where they can be hidden or shown. This allows additional modules to be added to the darkroom, like metadata editor and styles.

    • This replaces the options in the "collections" and "recently used collections" modules' preferences to show or hide the latter and show a "history" button in the former instead. Users that want the separate module will need to reenable it once via the new right-click menu.

    • The menu also contains an option "restore defaults" that resets the selection and position of modules in the current view. In the preferences dialog, on the general tab, there's a "reset view panels" button that resets all views, including visibility and width of the panels themselves.

  • Added a global preference to swap the left and right side panels in the darkroom view.

  • The first time a new user presses Tab, they will be warned that this will hide all panels and how to get them back. Hopefully this prevents some confusion or frustration.

  • Drag&drop utility module headers to reposition them across the left and right panels (lighttable) as well as vertically (all views). Hold ctrl+shift to avoid expanding/collapsing them before dragging. Each view can have a different layout.

  • Drag&drop of processing modules in the darkroom right panel has been improved to auto-scroll when reaching the top or bottom and to not get confused when images get dragged into the area.

  • Improved the message displayed at startup when the database is locked by another instance of darktable.

Performance Improvements

  • Added OpenCL implementation of color equalizer.

  • Improved the speed of bulk image operations by improving the speed of sidecar writes, and by moving sidecar updates for many operations into a background task, allowing the user to proceed before the writes complete.

Other Changes

  • Switched default scope for new installations from histogram to waveform to display more detailed information about image color and tonality.

  • The ISO 12646 color assessment condition is kept until unset by user action.

  • Exposure bias can now be used to form collections and as a display filter.

  • Improved visualization of the color equalizer's effect.

  • Improved debugging support for verifying CPU vs. GPU results.

  • Add Calibrite alias for X-Rite ColorChecker in color calibration.

  • The scan for updated sidecar files now ignores timestamp differences of two seconds or less.

  • Numerous rounds of code cleanup.

  • The macOS installation package now has a background image to direct the user on installing darktable.app.

Bug Fixes

  • Fixed a performance regression for redrawing mipmaps.

  • Fixed handling of old (2020) edits using Filmic RGB.

  • Various OpenCL fixes to reduce differences between CPU and GPU processing: colorspace conversion, saturation gradient filter in color equalizer.

  • Fixed gallery export not working on Windows.

  • Fixed printer discovery in the print module, which could cause available printers to be missed.

  • Work around out-of-spec ExIF date field caused by buggy software.

  • Fixed reading embedded color profiles from PNG images.

  • Fixed certain boundary cases in the crop module.

  • Fixed crash when loading corrupted .gpx file in the geotagging module

Lua

API Version

  • API version is now 9.3.0

Bug Fixes

Add action support for Lua

Other Lua changes

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.

  • Release 4.8 drops support for macOS versions older than 13.5.
