The bottom panel provides quick access to apply presets and styles to your image and allows to activate over/underexposure warning as well as softproofing and gamut check. You can also activate a filmstrip for quick navigation within the current collection.
Clicking the icon warns you about areas of your raw input image with clipped color channels. Clipped color channels imply an overexposed image with loss of information in the affected areas. You may use the highlight reconstruction module or the color reconstruction module in order to reconstruct those areas (see Section 18.104.22.168, “Highlight reconstruction” and Section 22.214.171.124, “Color reconstruction”).
The default “mark with CFA color” mode displays a pattern of the respective primary colors (red, green, and blue) to indicate which color channels are found to be clipped. In the “mark with solid color” mode clipped areas are marked with a user defined solid color (see below) independent of the affected color channels. In the “false color” mode clipped color channels are set to zero in the affected areas.
Selects the solid color for the “mark with solid color” mode.
This slider sets the threshold of what values are considered to be overexposed. You can leave it at its default value 1.0 (white level) in most cases.
By clicking the icon an over/underexposed warning is toggled on or off. Pixels outside the dynamic range, close to pure white or close to pure black, are prominently displayed in a signal color. You can also activate the over/underexposure warning with the keyboard shortcut “O”.
In the default color scheme underexposed pixels are shown in blue and overexposed pixels in red. These colors are easy to identify in most cases. In some cases you may want to change the color scheme to “black & white” or “purple & green”, eg. if you experience overexposed highlights in red blossoms.
Sets the threshold for underexposure warning, expressed as a percentage of the maximal brightness.
Sets the threshold for overexposure warning, expressed as a percentage of the maximal brightness.
Clicking the icon activates the soft proof display mode of your image. Soft proof allows you to preview your image rendered using a printer profile so as to see how colors will end up on the final print. You can also activate soft proof with the keyboard shortcut “Ctrl+S”. An information message “soft proof” on the bottom left of your image tells you that you are in soft proof display mode.
Sets the rendering intent for your display – only available if rendering with LittleCMS2 is activated. See Section 126.96.36.199, “Rendering intent” for available options.
Sets the color profile for soft proofing. darktable searches for available profiles in
used here to represent your chosen darktable installation directory and
$HOME your home directory. Typically these profiles are supplied by
your printer or generated during printer profiling.
Sets the color profile for the display. The option “system display profile” is the preferred setting when working with a calibrated display; the profile is taken either from your system's color manager or from your X display server. In GUI options (see Section 8.1, “GUI options”) you can specify which method to use. For more information see Section 188.8.131.52, “Display profile”.
Clicking the icon activates the gamut check display mode of your image. Gamut check highlights in cyan all pixels out of gamut with respect to the selected softproof profile. You can also activate gamut check with the keyboard shortcut “Ctrl+G”. An information message “gamut check” on the bottom left of your image tells you that you are in gamut check display mode. Gamut check and soft proof are mutually exclusive modes.
Right-clicking on the icon opens a dialog with configuration parameters – they are the same as for the soft proof option (see Section 184.108.40.206, “Soft proof”).
The optional filmstrip can be used to quickly switch between images while remaining in the darkroom view. The images viewed are the same as the ones in the lighttable view.
The filmstrip can be switched on and off using the shortcut Ctrl+F. You can change the height of the filmstrip panel by dragging its top.
You can scroll with your mouse to quickly navigate through the images. You can change the photo being processed by double clicking on another picture. You can also use Spacebar to process the next photo and use Backspace key to process the previous photo.
The picture currently processed is selected and highlighted; with a single click you can select any other picture from the filmstrip without changing the picture currently processed. With the Ctrl+A shortcut you select all the pictures of the filmstrip. With the shortcut Ctrl+Shift+A you unselect all images, and with Ctrl+I you reverse the current selection.
The following shortcuts are available to act on the selected picture(s):
|F1 – F5||toggle color label (red, yellow, green, blue, purple)|
|0 – 5||set/change image rating|
|Ctrl+C||copy the full history stack|
|Ctrl+V||paste all of the copied history stack|
|Alt+Ctrl+C||selectively copy the history stack|
