For this project, you'll remove details from an image you don't want in the shot. For example, a tree or someone in the background. For this assignment, you'll need to remove distractions from 2 different images. You don't have to worry about copyright for this project, but if you want to publicly share your work, you should use legal images.

Note: if you ever can't find a window or panel you're looking for, go to the top of the screen, click Window, then whichever panel you're looking for, such as Layers.
Also: if you get stuck, you should try googling what you're stuck on. There are soooooo many Photoshop guides - if this one is confusing to you, use Google as your personal guide! You can also contact me, obviously. Google will just be faster.
