This tutorial shows how you can do vignette effects using a new feature of GIMP called QuickMask.

QuickMask is a convenient way to modify selections using pixel-changing tools such as the paintbrush, eraser, or any plug-in filter. It lets you make very precise adjustments to your selections.

This tutorial doesn't use QuickMask for complex masking; it's intended to show how you can use it to create quick and easy vignette effects. It's even easier than my older vignettes tutorial.
