This is a nice green-screen video we did with a Parish about six blocks away from our studio. We wanted a light and bright feel for the interviews so we decided to go with a green-screen and then to replace the background in post. We started with just white but with one of our angles being wide, and showing the subject's whole body, it didn't look right. I ended up creating a digital cyc wall in After Effects and using digital lighting to give some depth to the background. Then I manually added shadows. The end result was a nice and bright background that blended well with our subjects.
Here's a link to the video in our portfolio.
