Polarizing filter is considering the most useful filter in landscape photography. If you are going for a day landscape shoot, do not leave house without one. The obvious reason of why people uses this filter, is that it has the ability to darken blue skies. However, they are equally useful in removal of reflection on non-metallic surfaces, such as reflection from water.
Having a polarized sky makes the landscape photograph look more appealing and can also help to create an attractive backdrop. Shooting any subject such as, people, building, bridge, mountain, against a polarized sky. Result will be bursting with impact.
How Polarizing work?
I need to be a little technical when comes to explaining this. Basically, light travel in straight lines, vibrating as waves in all angles and directions. When light hit an object, some lights in absorbed while some is reflected. The absorb lights define the color of the object.
From the reflection of light waves, polarized light is form and it only travel in one direction. This is the wavelength that created reflection, glare and reduce color intensity. A polarizing filter is made to block polarized light, thus restoring contrast and saturation.
How to use Polarising Filter
Polarising filter is made up of two circular piece of glass and then screw onto the front of your lens. Using a polarising filter on a DSLR camera is simple. Just turn its front part to adjust the effect and watch it appear in the viewfinder.Remember that the effect is stronger when you have the sun at 90° on your left or right. It will be less visible with the sun in your back and almost non-existent with the sun in front.
Here are the main situations in which I find a polarising filter is useful.
On Bright sunny day to darken sky.
Removal of reflection on water.
Removal of haze.
Getting Your Polarising Filter
There are no reasons of not getting a Polarising Filter especially in landscape photography. Before buying the filter, you must select which lens you want it to fit on, it is often the one that you often brought out for day shoot. Next, find out what size of the polarising filter your lens is using. The size is shown at the front of the lens, the image shown above is using a size 52 filter. I highly recommended HOYA Polarizing Filter which makes quality filter at a reasonable price.
