3.2.3. Module presets

Presets are stored configurations for a module's parameters. Some modules already have internal pre-defined presets but you can also define your own. Both internal and user-defined presets are displayed by clicking the icon with the currently activated preset shown in bold text.

The preset system also supports automatic preset selection based on image data such as focal length, ISO, camera model and other fields.

You can further refine the automatic preset selection on the image type like being raw, hdr or monochrome. (For automatic detection of monochrome images switch on detect monochrome previews in darktable preferences.)

As a convenience, a preset can be applied to a new module instance by pressing the middle-click. Creating a new preset

First configure the module's parameters then click the icon and select store new preset. The following dialog will be shown for configuring the preset:

The first two fields are used to name and describe the preset.

In the example above we have also checked the auto apply option. This brings up additional selection fields where you can define a filter used to decide if the preset should be automatically applied when opening other similar images in darkroom for the first time. The example dialog above sets up following rules: if lens name matches and aperture is greater or equal to f/8 and focal length is between 24 and 35mm the preset will be automatically applied. Also the second checkbox is clicked so this preset will only be shown in the preset list if the image matches the rule.

darktable finds this data in your image's Exif information. If you want a preset to be applied to all images from a specific camera leave all fields at default values except for the model field.

Tip: The image information panel for your image displays your model name, use this to ensure you have the correct spelling (see Section 2.3.5, “Image information”). Managing Presets

Both user created and pre-defined presets can be viewed and managed from within the presets menu (Section 8.12, “Presets”) in the preferences dialog (see Chapter 8, Preferences and settings).
