Nino Giannotti has put up a great website on lighting for anyone involved in Electronic Field Productions (EFP) and Electronic News Gathering (ENG), or just wanting to learn more about gear and technique. He explains the principles behind video lighting for basic interviews and more complicated setups, like multiple camera shoots and exterior stand-ups.
He explains how to make backgrounds out of simple fabric and use filters and gels to control colors. It’s a great site for learning more about different kinds of lights and lighting tools. Check it out here.
