Now, use the “Vignetting” filter in Darktable. As you can see, there is no vignetting on it. Sometimes you want to remove it, sometimes you want to add it for artistic or personal taste purpose ! Darktable has a filter to add vignetting to your picture. After correcting the vignetting and the lens distortion, the image results to appear flat, but of course more realistic. Removing only the vignetting and not the distortion resulted on a weird scenery because the vignetting can hide the distortion in an elegant way.īy the way, the two versions of the same picture present why I like the vignetting : First, the building and the water are nicely focused, and the distortion gives more deepness to the landscape.
The default mode will apply all corrections, but you can choose to remove only the vignetting, or fix the lens distortion.įor this example, I’ve preferred to apply all corrections. In the filter settings, you can choose which correction to apply. This is a distortion inducted by the lens shape.

It is usually an unintended or undesired effect caused by the lens, camera settings, or exposure. The vignetting in photography is a reduction of the image’s brightness or saturation toward its periphery.
