This is one aspect of landscape pictures that give life to the otherwise still frame. Flow of water when captured in a frame looks milky white and produces matte texture.
The trick to capture these flows is to slow down the shutter speed and let the lens capture the flow over time. If we are keeping shutter open for long, we tend to gather more light on digital sensor that necessary. Thus we must consider reducing aperture opening to some appropriate F value. This helps compensate the excess light and produces perfect exposures.
Normally bright daylight doesn’t demand usage of tripod but there are scenarios where tripod usage is recommended.
As discussed above while shooting Flowing Water and using slow shutter speed; one must consider using tripod for perfect stability. Tripod can be used when Auto Exposure Bracketing [AEB] is to be used. This ensures all the different exposures of the same frame can be correctly aligned to each other. This reduces the post-processing efforts of aligning the frames. Tripod can come in handy when shooting at night.
Note: Don’t over-use your tripod. No matter how light weight and portable it is, it definitely makes your kit heavy and trekking around can be treacherous.
Use of filters:
You can consider using two types of filters specifically when doing landscape photography.
Polarizing filter is like a friend of landscape photographers. It works on two levels:
1. Reducing reflections from the reflecting surfaces like Water surface, Metal bodies, Wet surfaces and so on. Thus helps prevent parts of the photograph from being over-exposed.
2. Making sky look more vivid. This adds lot of drama and life in the landscape photographs. They produce best results when placed at 90 degree angle to the Sun. Polarizers don’t really produce any great effects when Sun is directly in front or behind the camera.
Second type of filter is Neutral Density Filter. These types of filters are essentially a darker glass and simply acts like light ban. They reduce the amount of light that enters in the camera. We can use these types of filters where shutter speed is kept very slow and the image is getting over exposed. The variation of these filters is also available in which is darker at the top and clear at the bottom and shows a nice dark to light gradient. Specifically used when clicking over-bright skies.
