This sub-menu contains five effects which enhance or modify photographs.
The examples on this page show the effects being applied to an entire image - with the exception of Red Eye Removal. It is easy to restrict the adjustment to a sub-section of the image simply by making a selection. If a selection is active when the effect is run, it will only be applied to the selected region. Areas outside of the active selection will remain unchanged. See the Red Eye Removal effect for an example.
The controls shown in the effect dialogs operate in much the same way; drag the indicator left, right or in a circular motion (for an angle control).
Typing in a numeric value in the text box or using the up/down arrows beside the text box also changes the current value.
The keyboard arrow keys can be used to alter the value of a control once it has the focus.
Multiple controls can be used in isolation or combination. If more than one is altered, the cumulative effect will be shown.

This effect is new to paint.net 4 and is used to create a darkened circular halo around the edges of an image. This effect is commonly seen in portrait photography.
The color of the vignette created by this effect is not configurable from within the effect dialog.
It will always be black (or a subtle grayscale if the
