More and more small businesses are using video as a key element on their Web sites, and want to know how to do it better.So we headed to Hollywood where we visited the crew of the CBS television show "Criminal Minds" on location and talked with the director of photography, Greg St. Johns, whose job is to oversee lighting in setting a mood and to “choreograph the move of the cameras.”We talked to the cinematographer about how the switch from film to high definition cameras has changed the way he works and took a look at the state-of-the-art equipment.St. Johns also gave us some good tips about how to use lighting and props to make your videos look more professional.
