Photographing Waterfalls

Waterfalls and streams are popular photography subjects because they can easily be made into a soothing digital desktop wallpaper. A common element in many waterfall pictures is the silky smooth appearance of the water. This is not difficult to capture, with the right tools and techniques.

Tripod
Without a tripod, the pictures below would not have been possible. This is because we typically use shutter speeds of 2 seconds or more, which is not possible to hand-hold without getting camera shake.
Polarizing Filter or ND Filter
Circular polarizing filters are designed to reduce reflections and increase saturation. As a side effect, they also cut down about 1.5 stops of light coming through the lens.

ND filters are neutral density filters, available in different strengths. They act like sunglasses for your lens by cutting down the light coming into the lens.



Timing and Location

Finally it’s time to use these tools to get the shot. Shooting a time when the sun is not too strong will give you the best chance of slowing down the shutter speed. This is because even at ISO100 and F22, your shutter speed may not reach the required levels if there is too much light. A shutter speed range of 2 seconds to 5 seconds is your target. Shooting in forest cover will also increase the possibility of lower light levels.

Vary your shutter speeds for different moods. There are many other variables to fine-tune, like composition, color balance and foreground interest. So keep on experimenting to get the perfect waterfall shot.

Smoothening Ripples

You can also apply this technique on other water surfaces, like lakes and dams. Ripples on a lake can be smoothened out by using a long exposure. The result is a mirror-like calmness. Reflections on this surface are sometimes rendered as wavy surreal reflections. This was exactly the technique used for the 2 images below.
