Download darktable 5.2.0

The Big Ones
The following is a summary of the main features added to darktable
5.2. Please see the user manual for more details of the individual
changes (where available).
- View snapshots side-by-side with the current image, instead of as a
partial overlay, by clicking the button next to "take snapshot". The
center viewport is divided in two equal panels and can be zoomed and
panned (by dragging while holding the "a" key) as before. The
dividing line can not be moved and any click without "a" rotates the
layout.
- The metadata module is now fully configurable and allows to add and
maintain any tags which are supported by exiv2.
- Added a new module "raster mask import". After setting up a root
folder containing PFM files, a file can be selected to be used as a
raster mask, it is scaled to full image size. You can also define
what combination of the RGB channels of that PFM file will be used
for the raster mask.
- Sigmoid module is now the default tone-mapper selected for new
installation.
- The export module has got a new section multi-preset export which
allows to export the selected images with multiple presets in one
single export run.
UI/UX Improvements
- Replaced the zoom range widget, which controls the number of
thumbnails displayed on the thumbnail table, with a spin
button. This makes it easier to set the exact value.
- In the 4 ways tab in Color Balance RGB, ctrl+click now
picks the actual color while regular click continues to pick the
opposite color. This gives users more flexibility and control when
selecting hues.
Performance Improvements
- Eliminated unnecessary GUI refreshes.
- Improved user interface responsiveness for blending operations.
Other Changes
- Removed the levels and contrast brightness saturation modules (which
were deprecated in 2023) from the deprecated modules group. Since
this group would be empty after that, it has also been removed for
now.
- Due to an upstream issue, exporting JPEG XL in 16-bit float at
quality 100 is not currently mathematically lossless.
- Allow reading of files in Cineon format (developed by Kodak) and DPX
format (developed by SMPTE) with .cin and .dpx file extensions.
- The "prefer performance over quality" preference setting has been
removed.
- A workaround for old broken AMD OpenCL drivers that has been in
place for 12 years has been disabled by default. Hopefully more
recent drivers don't need it anymore and it caused problems with the
translation of the user interface during startup, causing part of it
to appear in English. If you have problems with OpenCL that you
believe may be caused by this change, please do two things:
- Add the line opencl_force_c_locale=anything to your
~/.config/darktable/darktablerc file.
- If that solves your problem, please report the issue to GiHhub
PR #18342, including information on the make of your GPU and the
version of your drivers. We can then for the next release either
by default re-enable the workaround for drivers that need them,
or warn people with antiquated drivers that they need to update.
- Presets can now be arranged in sub menus, like styles can, by
inserting | in their name between levels. The shortcuts
dialog/preferences tab now show these collapsible hierarchies for
styles and presets too (and the bug that style shortcuts were not
translated is fixed).
- Give a hint for pending background work when darktable is closing.
- Improved rendering output of Denoise Profile, Dither and Astrophoto
Denoise on second window or in high quality processing mode.
- Hide "reduce resolution of preview image" preference setting. This
was a way to get better responsiveness on slow systems introduced in
2020, but at the same time it was making the color picker and mask
support inaccurate (quality loss).
- Improved quality of inpaint opposed highlight recovery algorithm for
sRAW images.
- Reduced haze removal visible difference between exports and HQ
darkroom processing.
For some images the algorithm fails to calculate correction
parameters, this is reported via control log.
- Lens info is now read from OM-System/Olympus image files taken with
lenses without electronic data if this info is entered in the
camera lens info settings dialog. The lens correction module will
automatically find the lens, if it is supported by lensfun and the
entered name matches the lensfun name, which can be seen in the lens
selection drop down list.
- Raster masks got internal improvements and now support the same refinement
tools as all other masks including details threshold, feathering guide and
radius, blurring radius and contrast. Some UI refinements for raster-masks.
- The highlights module offers a raster mask with information about level above
clip level.
- Changing orientation (via the flip module) respects changes done in
crop module.
- The shown dimension while cropping now matches the default export
dimension and keeps the exact chosen ratio.
- In the history module item tooltip, fixed the formatting and scaling
of the changes to match the values as seen in the modules
themselves.
- Added auto login to the piwigo export module. This can be enabled in
the security section of the preferences.
- Add 45x35 aspect ratio to the crop module, which is popular on IDs
and passports.
- Color assessment conditions: Changed total border width to relative
scaling which should work well on small and big screens, independent
of physical screen resolution, added pop-up window for
parameterization and removed ISO12464 reference.
- Improved visibility of masks in darkroom. This is controlled by the
new hidden "darkroom/ui/develop_mask_mix" configuration option.
- Add a new setting to change which images are taken into account for
actions: By default, the image under the cursor takes priority. With
this parameter enabled, the selected images will take priority, and
the image under the cursor will only be taken into account to feed
the information modules.
- Added a tag icon on thumbnails to display the list of attached tags
when hovering over it.
- In the map view, it is possible to pan the entire track in one of
the following ways: by double-clicking on the track segment list, by
left-clicking on the list header, or by shortcut option.
Bug Fixes
- Fixed sidecar writing if quitting from darkroom.
- Fixed some rare race conditions while processing the pixelpipes.
- Fixed collection filter presets based on capture time creating an
empty widget.
- Proper high quality demosaicing and details blending support for
second window.
- Fixed a bug that allowed NULL pointer dereference in tethering mode
under certain conditions, which resulted in a crash.
- Fixed darktable shutdown code so pending background jobs are properly finished
and give a control log if there is pending work.
- Fixed a crash in the import dialog when trying to add a new place to
an empty places list.
- Fixed bit-depth setting not saved in AVIF export presets.
- Fixed reset button not working in the geotagging module. Also a
loaded GPX track in the geotagging module is now properly removed.
- Fixed darktable-cli crashing if the darktable database is locked.
- Fixed image not properly layout in the print module after being
rotated from Lighttable.
- Fixed a bug where the changes in various edit fields are not saved
correctly when the field loses the input focus.
- Fixed incorrect reporting of whether a flash was fired in expansion
variables $(EXIF.FLASH.ICON) and $(EXIF.FLASH) under certain
conditions.
- Fixed the edit style dialog to show all module's duplicates. Also,
when creating a new style we don't show the whole history but only
the last version of each module.
- Fixed a bug in xtrans demosaicers that could feed NaNs into the
pixelpipe.
- Fixed display of image using a composite module when the modules are
reordered.
- Many TIFF loader fixes and improvements:
- Fixed crash on files for which libtiff would issue warnings or errors
- Fixed crash on files with missing SAMPLESPERPIXEL tag
- Enabled CMYK TIFF support
- Added support for loading TIFF with missing/undefined sample format
- Fixed reading of grayscale images with min-is-white interpretation
(made them not inverted)
- Fixed regression in support of many more exotic variations
of the TIFF format, such as tiled encoding, planar layout,
uncommon bit depths (such as 12 or 14 bits, or less than 8)
Lua
API Version
