Leaving yourself open to criticism and suggestions will make you a better broadcaster.
In 1982, I was literally learning about television while working in television– the old PRISM–forerunner to today’s Comcast Sportsnet Philadelphia. I was editing a feature on the 1946-47 Philadelphia Warriors, the NBA’s first champions. A gentleman by the name of Roy Hensel suggested the concept of “audio sweetening,” that is, adding crowd noise or other effects to old black-and-white footage that was without a sound track.
It’s common practice of course, but being relatively new to TV, I had no idea. The suggestion—obvious and simple as it was—added depth to the feature, literally bringing the past more alive.
Leaving your ego at the door and being open to feedback from anyone you work with can only help YOU.
