PixelSnader Posted April 7, 2019 Share Posted April 7, 2019 Hey, I was wondering if anyone had figured out a way to use a mask, or a z-depth image to blur an image? In Photoshop you can use a black and white image to partially blur an image, to get a narrow depth-of-field effect: I've already tried to use a full-image blur with a mask, but that gives 80s-esque halo effects. The halo is there because the whole image (BG+dress) is blurred, while the dress should not be taken in to consideration for the BG-blur. It is quite noticable around the dress here: Anyone have a usable method for this effect in Affinity? Quote Link to comment Share on other sites More sharing options...
John Rostron Posted April 7, 2019 Share Posted April 7, 2019 Having selected your unblurred target (such as the dress and occupant), you need to cut it out (to the clipboard) using ctrl-X or cmnd-X. Then activate the gaussian blur filter making sure that you tick Preserve Alpha. Then paste your clipboard back nto your image using ctrl-V.or cmnd-V Ticking Preserve Alpha ensures that the blurring is not affected by the transparent hole.
