If you shoot lots of interviews you know that each one comes with its own set of challenges. If you travel to the subjects location you have to worry about how you will present the interviewers questions, getting shots of both parties, lighting, surroundings, audio, etc. Sometimes it's easy, sometimes it's a nightmare. Well one solution might be to do all your interviews with greenscreens then make them look however you want in post. In this article that's just what they end up doing. Heck, the interviewer isn't even required to be on location because they setup iChat so he can ask the questions while the subject answers into the camera. The interviewers part is all shot at another time and tweaked in post. The article is interesting and with everyone so busy these days it's certainly hard to get everyone in the same room at the same time. This is definitely something to keep in your hat to pull out when you need it.
