Generation

Flash sync speed is the fastest shutter speed at which your camera's shutter is fully open at one instant, allowing the flash to illuminate the entire frame evenly. At speeds faster than the sync speed (typically 1/200-1/250s for most DSLRs), the shutter works like a traveling slit moving across the sensor, so a flash would only light part of the image, creating a dark band. This limitation exists because the flash fires nearly instantaneously, while mechanical shutters need time to travel across the frame. To use faster shutter speeds with flash, you'd need high-speed sync (HSS), which pulses the flash continuously as the slit travels, though this reduces the flash's effective power.
