Briefly explain shutter speed and motion blur and one common misconception about it.

# Shutter Speed and Motion Blur **Shutter speed** is how long your camera's sensor is exposed to light. A fast shutter speed (like 1/1000s) freezes motion, while a slow shutter speed (like 1/30s) allows moving objects to blur across the frame. **Motion blur** occurs when subjects move during the exposure. The longer the shutter stays open, the more blur you'll capture from moving elements. ## Common Misconception Many people believe **motion blur only depends on shutter speed**, but it actually depends on three factors: - Shutter speed - How fast the subject is moving - How much the subject moves *relative to the frame* A bird flying across your frame at 1/500s might blur significantly, while a distant car moving at highway speeds might appear sharp at the same shutter speed—because it covers less distance within your frame. This is why you need faster shutter speeds for nearby action than distant action, even if the actual speeds are similar.
