Three years ago, Dawn Porter decided it was time for a change. So, after five years as a litigation associate in Baker & Hostetler’s Washington, D.C., office and another 12 at in-house jobs with ABC and A&E, she set her sights on making documentary movies.

An amateur photographer whose experience at media companies was limited mostly to advising producers on legal and ethical issues, Porter had no idea how to shoot or edit film at the time. Nonetheless, she felt her career as an attorney had equipped her with the kind of storytelling skills essential to being a successful documentarian.
