darktable 3.0.0rc1 released

We’re proud to announce the second release candidate for the upcoming 3.0 series of darktable, 3.0.0rc1!

As always, please don’t use the autogenerated tarball provided by github, but only our tar.xz. the checksums are:

When updating from the currently stable 2.6.x series, please bear in mind that your edits will be preserved during this process, but the new library and configuration will not be usable with 2.6.x any more, so making a backup is strongly advised.

New shortcuts have been introduced to quickly collapse borders, sidebars, histogram and navigation modules, allowing a new borderless editing experience.

Note that the new GUI requires Gtk+ 3.22 or higher to work properly.

IMPORTANT: The ‘preview’ and ‘preview with focus detection’ actions (previously Z and Ctrl+Z respectively) are now assigned to W and Ctrl+W in order to follow the convention of using Ctrl+Z for the “undo” function (Ctrl+Y for redo).

  • A new timeline view has been introduced in the lighttable.

  • A new ‘culling’ mode has been added to the lightable view. It displays a fixed number of consecutive images starting from the first selected, and allows you to pan & zoom them. The number of displayed images can be set by the user, and they can be navigated with the mouse wheel and keyboard.

  • A quite extensive rewrite of the lighttable view (including the filmstrip in darkroom view) has been made to greatly improve the overall performance. The lighttable is now usable on 4K and 5K monitors.

  • Added support for the new ‘raster mask’, a copy of a parametric mask which is stable during the whole pixel-pipe.

  • The processing order of the pixel-pipe can now be changed by using Ctrl+Shift+drag on the module headers to arrange them relative to each other. It is VERY IMPORTANT to understand that this feature is NOT for creating a more convenient GUI layout, but for changing the actual processing of the image. DO NOT USE THIS FEATURE unless you understand the reason behind the default ordering, and have a specific reason for changing it. The default order is still the correct order for most purposes.

  • The ‘color zones’ module now shows a histogram based on the chosen ‘select by’ channel, and if the color picker is in ‘select area’ mode, the range within the selected area will also be shown. By default, the spline adjustment is now similar to the curve controls, allowing you to add and delete nodes, but these nodes can still be moved with the old-style size control by selecting the ‘edit by area’ checkbox. There is also a new ‘strong’ processing option, and a new color picker which creates a curve based on selected image area.

  • A new module ‘filmic RGB’ which, like the previous ‘filmic’, is designed to replace ‘base curve’, ‘shadows and highlights’ and other global tone-mapping modules. This new version replaces the one introduced in 2.6.2; it should be easier to use, and it will reduce color casts. The old ‘filmic’ module is now deprecated and is only available on images where it was already used for editing.

  • A new module ‘tone equalizer’ is designed to merge the features of ‘zone system’, ‘shadows and highlights’, and (local) ‘tone mapping’ modules in a scene-referred RGB space. It brings an easy and safe way to remap tones locally, performing a quick zone-based dodging and burning using Ansel Adam’s zone system logic. The module provides an interface similar to audio graphic equalizers, with 9 bands (available as fixed sliders or nodes on a spline view), allowing you to selectively push or pull the exposure for each band in the range from blacks to specular highlights. It also features an interactive cursor that allows to push or pull the exposure gains directly from the image preview by simply hovering over an area and scrolling. It uses a guided filter internally to refine the dodging and burning mask, which preserves local contrast without producing halos along edges.

  • A new module for handling 3D RGB Lut transformations (PNG Hald-CLUT and Cube files are supported).

  • Many improvements to the ‘denoise (profiled)’ module. The degree of shadow denoising can be controlled, including the correction of color casts (mainly improves high-ISO images). “Auto” modes which infer some parameters from the profile are available, allowing users to create presets which are adaptive to various ISO values. The default values of the sliders are also adapted dynamically on module activation, giving a good trade-off between noise smoothing and detail preservation. The non-local means mode has 2 new options: one to coarse-grain denoising, and one to control the amount of fine detail to preserve. The controls now have soft boundaries, which means that users can use the keyboard to enter values outside the range of the sliders if they need to.

  • Along with selecting the ‘soft proof’ color profile, users can now select an additional profile for the color space of the histogram, color picker and overexposed checker. When gamut or softproof checks are active the histogram and color picker use the softproof profile, otherwise they use the new histogram profile (which is always used for overexposure checking).

  • A new setting for ‘working profile’ has been added to the input color profile module. This color space will be used by RGB modules between the input and output color profile modules.

  • A new color picker has been added to the parametric masking controls which adjusts the range sliders based on the selected area from the image. Click the picker button to adjust the input image slider, Ctrl+click the button to adjust the output image slider.

  • The ‘picasa’ target storage in the export module has been completely rewritten to support the new Google Photo API, and renamed ‘google photos’. It is again possible to create albums directly from the export module.

  • A new single-line image information display can be positioned at the top (left, right, or center) or bottom (center) of the darkroom view to replace the information previously overlaid on the histogram. The specific information shown can be configured in preferences.

  • The ‘tagging’ module is faster, and can now display hierarchical tags in a tree view. Tags can now be designated as ‘private’ (not exported by default), ‘synonym’ (to help search engines), and ‘category’ (not exported, for organizing the tag library). The metadata exported with images can now be configured in the ‘export selected’ module, allowing you to choose which main types are exported, as well as define values for specific tags based on formulas.

  • Many code optimizations for CPU and SSE paths. The tone equalizer module introduces a new optimization paradigm (GCC target clones), aimed toward users of pre-built Linux packages. The image-processing code will be cloned for several CPU generations (SSE2, SSE3, SSE4, AVX, AVX2) at compilation time, and the best-suited version of the code will be chosen by the system at run time. This experiment is to be generalized to other modules if proven successful, and will allow users of pre-built packages to get the same performance as if the program was specifically compiled for their computer. It needs GCC 9 compiler and does not yet work on Windows due to the lack of support of target clones on the OS side.

  • A new preference to expand/collapse a darkroom module when it is activated/deactivated.

  • The ‘collect images’ module has a new single-click option featuring range selection for date-time and numeric values.

  • The orientation of drawn masks using the ‘gradient’ shape is now clearly displayed with an arrow.

  • The ‘graduated density’ module has better accuracy when computing the rotation to avoid sporadic flipping of the gradient.

  • Make sure the OpenCL kernel code is recompiled when the driver version is updated.

  • Add color pickers for ‘split toning’, ‘graduated density’ and ‘watermark’ modules.

  • The color picker positions are kept during editing within a module.

  • The map view can zoom on the images of the selected collection.

  • The slideshow will now start at the selected images if any, and supports changing the delay between images. It will also now be more responsive when manually moving backward and forward through the images.

  • A new ‘basic adjustments’ module has been added. It allows to adjust the black level, exposure, highlight compression, contrast, middle grey, brightness and saturation. It also has an auto feature based on Rawtherapee’s auto levels that can work on the entire image or a user selected area.

  • A new ‘rgb curve’ module has been added. It has modes for linked and independent RGB channels. The curves and histogram can be displayed using the working profile or can be scaled to be 50% grey. A secondary color picker will add 4 nodes to the curve based on the area selected in the image: min, average, middle, and max.

  • A new ‘rgb levels’ module has been added. It has linked and independent channels, preserve colors option and is native RGB.

  • A new search box has been added to the module groups in the darkroom view, with configuration options to show only the module groups, only the search box, or both. Modules are searched for by (localized) name, and when displaying only the search box, the active modules are shown when the box is empty. A shortcut can be set for focusing the box.

  • A preview window has been added to the darkroom that displays the edited image on a separate window.

  • A new option ‘skip’ is added to the ‘on conflict’ setting on the export module which skips the exporting to existing destination files.

  • Allow to switch between clone/heal and blur/color modes in ‘retouch’ module after creating a shape.

  • An accels window has been added to summarize all available shortcuts and mouse actions available in the current context.

  • Dynamic shortcuts have been added for darkroom module sliders. They allow to change slider values with an accel + mouse scroll.

  • A zoom & pan feature has been added to lighttable full preview..

    When you say new GUI requires Gtk+ 3.22 are we suppose to install it separately? if Yes then I am on OSX, how to install it?

    Just install it. The osx package contains the libraries it needs.

    I was hoping that in rc1 the google photo export will work but still opens the browser and asks for verification code! also what is darktable-rs-identity executable?

    Again, you need an oauth2 or an API token from your google account.

    How to do that? Can you please guide me?

    What have you tried?

    Looks like information is here: https://support.google.com/accounts/answer/3466521?hl=en

    when i select google photos in export there a a login button, when I click on it simply opens the safari browser with current tab and in darktable google authentication windows open and asks for a verification code.

    in the browser it never opens a login window for google where I can login and give permission to darktable

    Just upgraded from 2.6.2 on Ubuntu. The new version is a huge step ahead.

    Lighttable is so much faster and more flexible.

    The new profiled denoise gives me better results. Compared to the old version I almost lose not details, only a slight sharpness decrease that I can compensate with sharpening easily.

    Editing feels much easier and faster, moreover my changes look more natural than in the old version.

    Currently I am experimenting with the new modules, will take some time and learning curve…

    To questions right now:

    1. I cannot find the buttons to highlight over- and underexposed areas in darkroom, where are they?
    2. Where can I find the themes for editing? /home/username/.config/darktable/ only contains the old darktable.css

    Ive noticed that in 3.0.0rc0 in full screen mode there were minimise, maximise and close buttons in the top bar, are they likely to come back in the final version? I thought they were quite handy.

    Hi @ToddRivers and welcome!

    Please: what operating system are you using?
    And: from where did you obtain that 3.0.0rc0?
    (Present version is 3.0.0rc1+22.)

    Have fun!
    Claes in Lund, Sweden

    Hello Claes,
    I’m using win10 64. I got the 3.0.0rc0 from Github, the Download is at the bottom of this page.

    OK. Seems to be a known behaviour:

    Hmmm not sure were talking about the same thing here, after pressing F11 and going full screen there were 3 min max and close buttons above the lightable/darkoom/other tabs which I havent seen on any other version of Darktable, at the time I thought they were a new feature for DT3.

    apologies for the misunderstanding if the resize bug did cause the buttons to appear.!

    I just reinstalled it and took this screen shot, if this helps

    Hmmmm… I just installed 3.0.0rc1 on a Win X partition – and it behaves the way I would expect, i.e. normal Win minimize/maximize behaviour.
    Sorry if I still misunderstand you :-((( (if so: please enlighten me!)

    Ok these 2 screen shots show how it was on rc0 and how it is on rc1, both screens are fullscreen after pressing F11, rc0 has buttons ,rc1 doesnt.

    hope this helps


    But the buttons re-appear (in rc1) if you click F11 again?

    Yeah but its not full screen if you press F11 again, and the buttons are the windows system buttons.
    Im going to guess that this was a “feature” that crept in via a bug and probably wont make it into version 3.

    Thanks for taking the time to answer.

    download release 3.0.0rc1 there it is fixed

    Hello Bernhard, I updated to rc1 pretty much as soon as it came out, the thing is I thought the new buttons were a useful new feature, being able to minimise in full screen without using the keyboard seem handy.
