I was just watching a commercial on Sci-Fi channel for the new show Sanctuary. They mention that they use green screen technology so the actors are basically in a empty room with green walls so they have to act as if they are in a castle or a subway tunnel which they are not then the computers do the rest.
I have seen the first 2 episodes of the show and I did notice that the lighting of the people was too washed out compared to their background. I think if they are going to do that they need to work on that lighting issue. It's a good show and I can get past that issue but it's kinda hard to not notice it. I mean, that technology isn't new, they use it in movies all the time, you'd think they had all the kinks worked out for a tv show.
