Darktable photography workflow application and RAW developer released new stable 4.6.1 yesterday!
The release finished the documentation for the new 4.6 release series, include translations to Ukrainian, Polish and Dutch.
And, it now performs image discovery asynchronously in the import dialog. Meaning that long parsing due to huge number of sub-directories and
files can be easily interrupted by selecting another place or un-checking recursive mode.
The release now drops support for macOS versions older than 12.5. Other changes are mostly bug-fixes. They include:
Fix memory and resource leaks in the QOI image loader.
Fix RGBE image loader.
Fix crashes when running low on GPU or system memory.
Fix OpenCL startup for various cards.
Fix compatibility issues with HDR created DNG files.
RawTherapee, the free open-source raw photo processing program, announced the new 5.10 release this Friday!
It’s been more than 1 year since the last stable release. The new release can now add multiple custom external editors that can be chosen in the Editor tab.
The Preferences dialog now has new Favorites tab to add/remove favorite tools. And, it includes option to change Lensfun database directory.
RawTherapee 5.10 now uses Exiv2 to hanle metadata, and it supports CR3 medata. It can recognize ICC profiles in user configuration directory, and support Raw files from OM Digital Solutions cameras.
There are several Lightroom alternative applications for editing your photos. LightZone is one of them works in Linux.
It’s a free and open-source professional-level digital darkroom and photo editor written in Java. It has less features than the popular Darktable and RawTherapee, but it’s good at processing black and white photos.
Type user password (no asterisk feedback) when it asks and hit enter to continue.
2. For Linux Mint and old Ubuntu 18.04, user need to manually refresh the system package index by running command:

After installation, search for and launch the editor either from start menu or ‘Activities’ overview depends on your system.
Uninstall LightZone
To remove the photo editor, open a terminal window and run command:
sudo apt remove --autoremove lightzone
And remove the PPA repository either via “Software & Updates” utility under Other Software tab, or by running command:

Dual-demosaic algorithms, making use of the new contrast threshold mask, allowing one to use a combination of demosaicing algorithms where one is best for details and the other best for plain areas.
New color toning methods: Grid and Regions
Support for Blackmagic and Canon Magic Lantern lj92 encoded files.
New Soft Light tool which enhances contrast and saturation by emulating the effect of blending an image with a copy of itself in “soft light” blending mode in GIMP.

Open source Raw image processor RawTherapee 5.4 was released a few days ago. Here’s how to install it in Ubuntu 16.04, Ubuntu 17.10, Ubuntu 18.04, and derivatives.
New features in RawTherapee 5.4 include:
New default processing profiles, now the default look for raw photos closely matches the out-of-camera look with regard to tones and includes lens distortion and vignetting correction.
New histogram matching tool, to have RawTherapee automatically adjust the image for you to match the out-of-camera look with a single click of a button.

Added support for showing out-of-gamut areas based on the output profile.
Added support for reading and writing metadata and ICC profiles to and from PNG images.
Added support for processing Sony Pixel Shift ARQ raw files – make sure that the ARQ extension is enabled in Preferences > File Browser > Parsed Extensions.
Create Sony ARQ raw files using https://github.com/agriggio/make_arq
Added support for saving 32-bit floating-point TIFFs clamped to [0;1].
Added profiled chromatic aberration correction support using Lensfun.
More tools now have an on/off switch.
The user interface is cleaner, with all power-house tools moved into a new “Advanced” tab to prevent slider-shock to newcomers.
The Metadata tab now lets you choose whether you want to copy metadata unchanged, edit metadata or strip metadata when saving images. Now you can also make metadata changes in batch mode.
The choice of whether the main histogram should display information using the working profile or the output profile is now available from the Editor tab’s top toolbar.
The Crop tool’s aspect ratio now defaults to that of the image, and RawTherapee automatically zooms-to-fit the crop once it’s placed.
RGB input-type ICC profiles can now be used as output profiles.
The saved reference image for profiling (created from within the Color Management tool) now contains metadata.
PNG and compressed TIFF images make use of better compression.
Shortcut key changes: Zoom-to-fit the crop using “f”, fit the whole image using “Alt+f”.
