Focus peaking is a focusing aid in live preview or electronic viewfinders on digital cameras that places a white or coloured highlight on in-focus edges (contours) within an image using an edge detect filter.{{Cite web |last=Barbiaux |first=John |date=2013-04-07 |title=What is Focus Peaking? |url=https://www.photolisticlife.com/2013/04/07/what-is-focus-peaking/ |access-date=2023-04-27 |website=PhotolisticLife |language=en-US}}
