What is a synced shutter speed and why is it important for flash photography?

• A. The shutter speed used when flash is not used, to keep ambient light separate.
• B. The shutter speed at which the camera synchronizes with the flash to prevent dark bands.
• C. The fastest shutter speed the camera can achieve without any lighting.
• D. The exposure setting that has no relation to flash.

Answer: (B)

Synced shutter speed is the speed at which the camera’s shutter and the flash fire together so the entire frame is exposed by the flash. With most cameras, there’s a maximum flash sync speed, and at or below this speed the flash can illuminate the whole sensor evenly. If you shoot faster than that, the shutter curtains move across the frame while the flash fires, causing dark bands or partial exposure. That’s why staying at the sync speed (or slower) is essential for reliable, evenly lit flash photography. You can still control ambient light with longer exposures or use advanced modes (like high-speed sync) if you need to go above the sync speed.
