When I first began using photoshop, I was overwhelmed. The amount of tools you have and options is a lot to take in for a beginner. I’m going to explain how to do a mirror replacement with photoshop. It’s actually relatively easy when you know what tools to use. The quick selection tool makes it easy to erase the mirror in order to replace it with another one. A basic understanding of using layers of images for your final image as well is all you need to get started.
