You've already taken pictures and video of yourself with Mac's Photo Booth from the comfort of your own home, but how about from a sunny beach? Or a moving roller coaster? Photo Booth allows you to change the background of your pictures, and create custom backgrounds of your own, without leaving your home.
Set up the area where you will be filmed. You must be standing in front of a completely plain backdrop for the change to take effect. Make sure there is enough light on you as well; if you are in a poorly lit room, your videos will come out dark.
Open Photo Booth by clicking on the icon on your dock. If you don't have the icon, search for it in spotlight with the magnifying glass in the upper right corner of your screen.
Click "Effects," which is located under the preview, on the right side of the window.
Scroll through the effects until you see the backgrounds page. It will be the only page that is not a distortion of your image, but a silhouette in front of different images.
Choose the background you wish to switch to, then click on it. Step out of the frame so that the program can recognise the backdrop behind you. When it loads the new background, you can step back into the frame. The camera will pick up anything that is not the background it originally captured.
One screen of effects is all empty boxes that say, "Drag background here." You can make your own backgrounds by dragging any image you want into these spaces
