In this Photoshop tutorial, we'll learn how to create a high key glow effect, which is a fancy way of saying we'll be applying a glow only to the highlights in an image. This effect works especially well with wedding portraits since it's great for adding a romantic, magical look to your photos, and wedding portraits usually contain lots of bright white areas to work with. We'll see how to easily select just the highlights in an image using Photoshop's Color Range command, then we'll copy the highlights to their own layer and create the glow effect using a blur filter and one of Photoshop's layer blend modes designed for lightening images. Finally, we'll combine layers into a layer group and use a layer mask to limit the areas where the glow effect is visibile. It may sound like a lot of work, but once you know how to do it, the entire effect can be completed in just a few minutes! I'm using Photoshop CS4 here, but any recent version of Photoshop will work.
