What’s the Difference? is a series of video lighting tutorials. Each episode responds to a single question. In this episode, Jared Platt compares shooting in TTL and Manual Mode. The entire series, including all videos, articles and lighting diagrams, is available at our website. And feel free to leave a question to Jared in the comment section if you have one!
We were on location to photograph musical recording artist Mindy Gledhill and her tour bus. It was a beautiful sunny day, so the side of the bus was fully lit. This made it perfect to test our Profoto B1 and B2 Off-Camera Flashes in TTL Mode.
TTL is short for through-the-lens flash metering. With either an Air Remote TTL-C or an Air Remote TTL-N mounted on their camera, a photographer can set up her lights, turn them on and fire to get a perfect flash exposure. Then, with the touch of a few buttons, the photographer can adjust the TTL flash compensation right in the camera itself, and when using various groups, can raise and lower power on three separate groups (A, B, C) independently from the camera in TTL and Manual Mode.
