How to use Photo Overlays? This tutorial will show you how to use overlays, Photoshop Actions and Lightroom Presets to make photos beautiful (without needing any photography expertise). Step One: Paste the Overlay To begin testing, paste a some overlay into Photoshop as a new layer. Resize the overlay until it completely covers the image underneath. Try out different colors, shapes, and compositions until you think you’ve found the right match. Step Two: Select the Blending Mode With the layer mask selected, click on the blending mode button and select “Screen.” Step Three: Edit the Layer Sometimes an overlay will obscure parts of your image, so a little editing might be necessary. Step Four: The Finished Product Your image is complete! As we said before, sometimes it takes a few tries to find the right overlay to go with a photo. Luckily, adding overlays is pretty easy, so you can test out as many overlays and images as you’d like.
