I needed a green screen, and to begin with, it is a miscellaneous product. I asked the guy at Soundtrack where to get one or if they had one, and he gave me some websites to go to that sell them. Well, the green screens ended up being $80 at the cheapest, and I couldn't spend that much money for a green wall. So, I came up with a killer idea. I went into OfficeMax and saw some bright green poster boards for $0.99 each, so I bought a few, tacked them up on my basement wall, and it works great! I had some problems with lighting, but it was my first time keying graphics, so that was expected. I did a newscast in front of it, and placed a LiveType texture behind me using Chroma Keyer, and I must say I am proud of what I did. So, in conclusion, when looking for a green screen, just go to OfficeMax and buy some posters!
