While it certainly wasn't my first time using one, a recent shoot I did for TEDx at the Ohio State University made me realize how much easier life is with a light meter. For almost all the time I've spent behind cameras, I've been creating portraits. And for most of that time, I've been using flash. Starting out, I would just shoot and tweak power settings and my aperture and the light placement until I got what I wanted. As an amateur, it worked. But once I decided that photography was a career for me and as I began picking up client work, this method became quite ineffective, forcing me to get the one tool I never realized I needed.
