Pre-Release Capture Explained: Photographing the Past

A toucan peers out of its nest and seems ready to take flight at any moment. I wait eagerly in the hide, my finger on the shutter button, determined not to miss the moment when it flies out and spreads its wings. Cut to an hour later. I blink, I open my eyes, and the toucan leaves the cavity. My panicked brain processes what happened, then sends information through my spinal cord and a few peripheral neurons to my index finger, which finally presses the button. Damn, too late! But it didn’t have to be like this. Many of today’s cameras solve the problem of human reaction time with a feature known (among other names) as Pre-Release Capture. Let’s take a closer look at it today.
