In this lesson, Tim Babiak explains how flash photography interacts with your camera’s shutter speed and why flash exposures behave differently from constant light. You’ll learn how focal plane shutters work, what first and second curtains do, and why fast shutter speeds can create black bars or burned edges in your images when you go past your camera’s flash sync speed.

Tim walks through typical sync speeds like 1/200 or 1/250 second, shows what happens when you exceed them, and explains how to keep your flash in sync for clean, evenly lit frames. This segment is essential for photographers who want reliable, professional flash results and a solid understanding of how shutter speed, flash duration, and sync speed all work together.
