Thanks guys,
Lot of really great advice here. I need to use a fill light more.
Often, I do not use a frontal fill for two reasons: One, I love to move the camera, maybe even too often. I love a slight dolly or jib move. Second, I love contrast in my shots and on my actors faces. I love large soft sources close to the subject so the light just kinda wraps around there face and then falls off into deep shadows. So tend to use high key / fill ratios.
So what are some ways to fill without making my image look too flat. Also , how can I fill and not tie down my camera or battle shadows all day. Thanks again, I'm taking notes! :P
