Waterfall Long Exposure: Settings and Gear

Moving water is the easiest place to learn long exposure, because the effect is immediate and dramatic. A shutter speed around 1/4 second keeps texture and streaks in the water, 1-2 seconds gives a smooth silky flow, and 10-30 seconds turns a cascade into soft mist. Which one you want is a creative choice, but you must be able to reach those speeds in daylight.

To get seconds-long exposures in bright conditions you cut light rather than close the aperture. A neutral density filter is the tool: a 6-stop ND covers most waterfalls, while a 10-stop ND lets you shoot 30-second exposures in full daylight. Add a polariser to remove glare from wet rocks and foliage and deepen the greens. A sturdy tripod, a remote release or the two-second timer, and manual mode with ISO 100 and f/8-f/11 complete the setup.

Focus manually, and switch off image stabilisation once the camera is on a tripod. Cover the viewfinder eyepiece so stray light cannot leak in during long exposures, and check the histogram, because white water clips easily: expose so that the brightest foam still holds detail. Overcast days are ideal, with soft light, open shadows and shutter speeds slow enough that you may not even need a filter.

Watch for spray on the front element; keep a microfibre cloth handy and check for spots between frames. Include a rock, a fallen log or a person for scale, and resist centring the fall in a frame of black wet stone. Finally, stay back from slippery rock and never step into a river you have not judged properly.
