Here’s How to Shoot Razor-Sharp Photos in Low Light by Using the AF Assist Beam on Your Flash (VIDEO)

How often have you captured what you thought was a great photograph, only to learn later that your “money shot” was soft and destined for the trash? We all miss focus on occasion, especially in low light, but the quick video below will help you keep those mistakes to a minimum.

David Bergman is a professional sports and celebrity photographer, and he begins this tutorial with a simple reminder: “Your camera’s AF system needs light to focus.” In just two minutes, Bergman demonstrates the simple trick of using the AF assist beam of an on-camera flash, to dramatically improve your batting average when shooting in dim conditions.

The AF assist beam is that red grid pattern emitted by a flash unit, and it can be a real lifesaver in achieving accurate focus, IF you use it correctly. And that’s what you’ll learn to do in this episode of Bergman’s Two-Minute Tips on AdoramaTV.

As Bergman explains, your focus point needs to be on or near the middle of the frame for this technique to work properly. That’s because the AF assist beam is ineffectual around the edges. It’s also important that you select the correct mode on your flash.

Bergman also demonstrates a few other uses for the AF assist lamp, including how you can use it to improve focus without actually using the flash to illuminate the scene. We bet that after watching this video, using the AF assist beam will become one of your favorite tricks.
