In the same composition, use Select>Color Rangeâ¦to select the high-lights of the base image. Be generous with the Fuzziness, as detail won't be an issue. Copy the selection to a new layer (Command – J [PC: Ctrl – J]) and set its blend mode to Screen, which works kind of inversely from Multiplyâ”blacks become invisible and whites are added. The result is a simple bloom or glow effect.
I love this tip! Simple & quick but a very cool effect.
Thank you. Rhonda
