If you want to brighten your background in Photoshop, there are a few things you can do. One is to use a layer mask. This is a tool that lets you control how the background color appears on different layers. Another thing you can do is to use a gradient. A gradient is like a color wheel, and it lets you create different colors by mixing different colors together. Finally, you can use an adjustment layer to change the brightness and saturation of the background.
