There are a few things you can do to defringe in Photoshop to make your photos look more realistic. The first is to use the Defringe tool. This tool will help you to move and resize pixels around your image, making it look more like it was taken from a real-life photograph. You can also use the Curl tool to make the corners of your image look sharper. Finally, you can use the Levels tool to adjust the brightness and contrast of your photo.
