Moving water can be shown as fog-like vapor by using _____ shutter speeds.

• A. Fast
• B. Slow
• C. Medium
• D. Very fast

Answer: (B)

When water is moving, the brightness you capture depends on how long the shutter stays open. Slow shutter speeds let the motion play out over a longer time, so the water’s movement is blended into a single, continuous blur. That blur smooths the texture and creates a soft, fog-like or misty appearance. If you use a fast shutter speed, you freeze the motion, and you’ll see sharp waves and droplets rather than a hazy veil. A medium speed won’t give you the same ethereal softness because the motion isn’t integrated long enough to resemble fog. To achieve this effect well, shoot with a tripod, and consider techniques like using a neutral density filter or shooting in lower light to keep the exposure long enough without overexposing.
