Here is the second installment of my lessons learned while photographing foliage.
Lesson 3: Equipment
Taking photos of waterfalls and streams require the camera to be still for a second or longer and often in water or at awkward positions along streams. A tripod is an essential piece of gear. Make sure your tripod head can support your camera and heaviest lenses. Seems simple enough but make sure you test horizontal as well as vertical camera positions. You may be surprised. This is one area where you truly get what you pay for.
To keep the camera still and take the photo, a cable release is highly recommended. They are fairly cheap (under $30). I would go with a cable rather than a wireless release. The reason is that the cable gives you the ability to keep the shutter open for long night exposures. A wireless one that can do that is more expensive and not as reliable.
To make colors pop and to reduce the glare of the water, a polarizing filter is a must have. They vary in size so you’ll need to know what lens you are using it for. They also range in price and can get expensive fast. But if you decide to shoot a lot of water, it is worth the money.
