There are a few things you can do to cut out a shape from an image in Photoshop. The first is to use the selection tool, which is located at the bottom of the screen. This will allow you to select a part of the image and then drag it around. You can also use the arrow keys to move the selection around. The next step is to use the crop tool, which is located at the top of the screen. This will allow you to select a specific area of the image and then crop it out. Finally, you can use the layer masking tool, which is located at the bottom of the screen. This will allow you to mask out certain areas of the image and then create new layers with different shapes inside them.
