# Vignette > Darkening or lightening towards the edges of an image, either a lens fault or a deliberate effect. Also known as: vignetting. Category: Lighting and optics. A vignette is a gradual change in brightness towards the edges of an image. As a lens fault (vignetting) it darkens the corners; as an editing effect it draws the eye to the centre or evens out the background. ## How PhotoRobot uses it PhotoRobot Controls has a Vignette function with a configurable gradient and shape for painting image backgrounds, which PhotoRobot notes is especially useful with the Turning Platform. ## See on photorobot.com - [Image editing tools: vignette](https://www.photorobot.com/software/image-editing) ## Related terms - [Turning Platform](https://www.photorobot.com/glossary/turning-platform): PhotoRobot heavy-duty turntable for furniture and machinery, with plates up to 280 cm and a 1500 kg load capacity. - [White background](https://www.photorobot.com/glossary/white-background): A background of pure white (RGB 255, 255, 255), standard for e-commerce product images. - [Post-production](https://www.photorobot.com/glossary/post-production): Everything done to images after capture: editing, background removal, cropping, export. ## Where this term appears on photorobot.com Mentioned on 2 pages.
