In photography and videography, I find that a green screen is an essential backdrop to have on hand. It is right up there with the standard white, gray, and black backdrops. So, knowing how to make your own green screen can really come in handy. However, the products required to make a green screen can be very cost prohibitive, especially if you are just starting out and are on a very tight budget. And in my case, if you are a total DIYer who wants the most bang for the least buck.
