Shutter Speed Guide: Freeze Action or Blur Water
DefinitionThe length of time the camera sensor is exposed to light.
1The Simple Explanation
A fast shutter (1/1000th of a second) freezes time. A slow shutter (1 second) lets moving objects blur. Handheld photos need at least 1/60th to avoid shake.
2Technical Deep Dive
Measured in fractions of a second. Doubling the time doubles the light (1 stop). Sync speed (flash) is typically 1/200s.
Common Misconceptions
Myth: Fast shutter makes the photo darker. Fact: Yes, it does. You must compensate with Aperture or ISO.
