Darktable 4.8.0 Adds Color Equalizer, Enlarge Canvas, & Overlay Modules

Darktable, the free open-source raw image processing software, released new 4.8.0 version this Friday!

Darktable 4.8.0 introduced a few new modules. They include the color equalizer module, allowing to control hue, lightness, and/or saturation based on colors.

There are as well new Enlarge Canvas module, allowing to add areas on top, bottom, left, and/or right of the image, and fill with different colors, or some other part of the image by using Retouch module.

By drag-and-dropping from the filmstrip to the new Overlay module, it can now add overlay on top of current image. And, the overlay can be scaled, rotated and shifted horizontally or vertically.

The release also implemented a toggle switch for the darkroom mode, forcing the pixel-pipe processing to use the whole image data instead of just the area displayed.

Other changes in Darktable 4.8.0 include:

• Much faster map view on large collections.
• Add Apple Keychain password storage backend for macOS devices.
• Add Windows credential manager password storage backend.
• Remove AI options in color calibration module.
• Ability to import images in-place in a GVfs mount on Linux.
• Add support for DNG files, requiring the CameraCalibration tags for correct white balancing.
• Add support for CMYK profiled histogram.
• Drop support for macOS older than 13.5.
• various other improvements and bug-fixes.

Or, install Darktable via one of the below methods:

• Flatpak package, runs in sandbox environment.
• Native .deb package, via either OBS repository or Ubuntu PPA.
• Snap package, runs in sandbox environment.

Option 1: Native Deb package

For those who hate running app in sandbox environment, the native Darktable packages for Debian, Ubuntu, Fedora, and OpenSUSE are available to download at this OBS page.

For choice, Ubuntu 22.04, Ubuntu 24.04, and Ubuntu 23.10 on either amd64 or arm64 platform can run the 3 commands below one by one in terminal (Ctrl+Alt+T) to install the most recent release from Ubuntu PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/darktable

sudo apt update

sudo apt install darktable

Option 2: Darktable Flatpak package

The Darktable Flatpak package runs in sandbox environment, and can be installed in most Linux, including all current Ubuntu release, and even old Ubuntu 16.04 and Ubuntu 18.04.

Linux Mint 21 and Fedora Workstation (with 3rd repository enabled) can directly search for and install it from either Software Manager or GNOME Software.

While, Ubuntu users can press Ctrl+Alt+T to open up a terminal window, and run the 2 commands below one by one to install the package:
