fill light (deprecated)
Please note that this module is deprecated from darktable 3.4 and should no longer be used for new edits. Please use the tone equalizer module or the exposure module with a drawn mask.
Locally modify exposure based on pixel lightness.
This module pushes exposure by increasing lightness with a Gaussian curve of a specified width, centered on a given lightness.
- The fill-light exposure (EV)
- The median lightness impacted by the fill-light. The lightness must be set manually but a color picker can be used to provide a guide based on a sample from the image. The lightness of the selected point/area is displayed in the gradient bar.
- The width of the Gaussian curve. This number is expressed in zones, with the full range being 10 zones.
