In theory, you don't even need an actual green screen - just a flat surface with a uniform colour that doesn't match any you/the subject/s are wearing (ditto hair/skin tone). Chroma keying works by looking for one identified colour and removing it.

The video below is an example of how you might deploy this technology; I filmed my IGS Media Technician John against a greenscreen (having provided a script), then edited this into a guide on using the greenscreen technology.
