Vignette

Vignette is a simple-to-use plugin developed for Paint.net, which gives you the possibility to apply a vignette filter to your photographs.

It features practical options that can be handled not only by advanced Paint.net users, but also by those just starting to get to know this program.

In order to get this extension up and running, it's necessary to download and copy the DLL file to the "Effects" directory of the image editor. It works not only with the installed version of the tool, but also with its portable counterpart.

If the application is currently running, it must be restarted to finalize setup and gain access to the new add-on. Once you've opened an image, you can launch the new plugin from the "Artistic" submenu of the "Effects" menu. The default settings of the vignette filter are automatically loaded.

It has a single panel for controlling properties, so you don't have to waste time navigating multiple windows. It's possible to set the vignette power and effect on the vertical and horizontal axis either by moving three sliders, typing the numerical measurements, or by clicking on two small arrow buttons to increase or decrease the numbers.

Moreover, you can set the RGB channels to the primary color as well as invert the transparency. Worth noting is that the picture modifications can be previewed in real time. This way, you don't have to commit changes just to be able to check out results and undo the action or remove the second layer if you're not pleased with the outcome.

Although it hasn't received updates for a long time, Vignette integrated with the latest edition of Paint.net in our tests without any issues. It didn't cause the utility to hang, crash or display error dialogs. Too bad that doesn't give you the possibility to change the focus point.
