The concept of equivalent exposure can be a tricky one to wrap your mind around when you’re just getting started in photography. Photography enthusiast and animator Vincent Ledvina of Apalapse made this helpful 5.5-minute video that explains it in a simple and visual way.
Ledvina also created a handy chart showing full-stop intervals of aperture, ISO, and shutter speed.
