It can be scary to add a lot of color to your light. But it's easy to underestimate how much color it takes to transform a scene and set a mood. Don't be shy. Those gels won't bite.
This nighttime portrait of soprano Alexandra Rodrick was a big step for me. It was made about five years ago, when I was just starting to realize how color-fluid real light could be. I kinda knew it, but I still didn't have the nerve to actually do it.
