Waterfalls do present themselves as a wonderful and challenging subject matter to photographers. Firstly they’re beautiful places, secondly they are often in tricky lighting situation and thirdly they’re a dynamic subject as they’re moving (and of course movement means a challenge but also a real opportunity for a more dynamic shot). A lot has been written about the finer points of photographing waterfalls but the basics are fairly simple.
Working with Movement
Anytime you’re presented with a moving subject a photographer really has two options. Firstly they can freeze the motion by using a fast shutter speed and secondly they can capture and enhance the motion by using a longer shutter speed that blurs the moving element in the shot (in this case – water). Most photographers take the second option and allow the water to blur. Here’s how to do it. You’ll need your digital camera and a tripod. It will also be helpful to have a polarizing filter if you have one.
How to Photograph Waterfalls
Take a Control Shot - Before you start experimenting – switch your camera to auto mode, make sure your flash is turned off and take a shot of the waterfall. As you do – take notice of the exposure that the camera sets. Your camera will almost certainly choose an exposure that freezes the water somewhat.
Shutter Priority Mode – Switch to shutter priority mode on your camera. Generally you’ll want to try to get a shutter speed of 1 to 2 seconds to get a nicely blurred water.
Tripod – Of course to take a shot at a shutter speed of this length you’ll definitely need a tripod or some other way to ensure that your camera is completely still for the full time that the shutter is open. Sounds easy doesn’t it – attach your camera to a tripod, switch to shutter priority mode, set your shutter speed to 1-2 seconds and take the shot. Unfortunately in most cases it’s not that simple.
The problem with increasing the shutter speed is that it increases the amount of light that gets into your camera and unless it’s quite a dark and gloomy day you’ll find your image is going to be over exposed (even though in shutter priority mode the camera will choose a very small aperture to try to compensate for it).
Other Tips to Try to Get Exposure Right
There are a couple of things that you can do to decrease the amount of light coming into your camera and get your exposure levels better:
Timing – pick the right time of the day to do your waterfall photography and you can definitely give yourself more options to use longer shutter speeds. Around sunrise and sunset are obvious times as light is less bright. Also overcast days are better than bright ones.
Filters – using a filter that cuts down the amount of light entering your camera can help also. There are a variety of filters available that do this but use a polarizing filter as it not only cuts down the light getting in but also can help you improve your shots (they cut down on reflections in shots – and waterfalls can have quite a few of these). Another type of filter you might like to use is a neutral density filter which is a filter that cuts down the light entering your camera – almost like putting sunglasses on.
Aperture Priority Mode - if you are still having trouble with exposure even at darker times of the day and with the use of a polarizing filter another approach that you can take is switch into Aperture Priority Mode and choose the smallest aperture possible. On most cameras this will be f/22 or f/36. The result of choosing this is that your camera will automatically choose the longest shutter speed available for that aperture. It may not be 2 seconds – but it will almost always be longer than the shutter speed in that first control shot that you took and as a result, the water will blur more than in the first shot. The other impact of having a smaller aperture is that you’ll have a larger depth of field and more of the waterfall will be in focus.
Low ISO – Choosing a lower ISO will mean that your camera’s sensor is less sensitive to light and will need the shutter to be open longer. It will also mean less ‘noisy’ or grainy shots which will give your shots lots of nice detail.
More Waterfall Photography Tips
Of course getting the exposure right is just part of the equation when it comes to photographing waterfalls with you digital camera. Here are a few extra tips.
Bracket your Shots
Take a series of shots at different shutter speeds and apertures - doing this can capture a variety of very different images of exactly the same scene with changes in the extent that the water blurred, changes in the depth of field and changes in the way the camera captured color. Also use your cameras built in exposure bracketing (check your manual) and bracket your shots in this way also.
Composition
Waterfall could be photographed from many angles and in many different ways ranging from the wide angle shot that puts the waterfall into its wider context right down to tightly cropped shots that focus upon just one small part of the waterfall. Also look for the different ways the water flows. In some places it’ll be multiple streams, in others it will gush explosively everywhere and in others it will flow gently in a single stream. Try a variety of positions on the waterfall (you’ll find that it’ll flow at different speeds in different sections also) and experiment with how the different parts look at slow shutter speeds.
Tidy Up
A little tidying up of your scene can have a big impact upon a waterfall scene. Before taking shots, scan your eye over your frame and look to see if there are any distracting elements that might be able to be moved. Particularly look for litter but also consider leaves on rocks etc. Simply tidying up the image in a way that doesn’t do any physical damage to the location can take your images to the next level.
Don’t Become Obsessed with Blurred Water
The effect of silky smooth moving water in your shots is difficult to resist but don’t let it become the only type of waterfall image that you capture. Try taking some shots with ultra fast shutter speeds also. This can especially be a powerful technique on raging waterfalls where there is lots of spray and explosive splashes. The other impact of faster shutter speeds is that you’ll need to use a larger aperture which means narrow depth of field which will bring a whole new impact to your shots.
Get out and Experiment
That’s enough theory – now it’s time to get out and do it because the more you do the better you’ll get. Have fun!
