Hoya Circular Polarizing Filter |
One way to control an image’s appearance as well as quality is to
incorporate filters in one’s photography. Camera filters enable a
photographer to achieve several imaging effects from correcting light to
adding a soft focus to diffusing color.
With the use of camera filters, the photographer is able to literally
bend light in order to alter or correct the image. Examples of lens
filters are haze filters which effectively reduces blue light and
skylight filters which provide a little warming to photographs taken
outdoors. However, for the outdoor photographer, one of the most
essential camera filters that must be in their kits is the circular
polarizing filter.
This type of filter is a type of filter that primarily removes
unwanted reflections from different non-metallic objects such as glass
and water. These types of filters also enhance the colors in the sense
that they saturate colors and make them appear clearer. They also
improve the overall contrast of the colors with each other. This type of
effect makes skies bluer and increases the contrast that they have with
the white clouds.
Hoya is one of the biggest and best names in optical filters. They
have introduced a thinner version of their circular polarizer which has a
slimmer mount which makes it exceptionally light and compact.
The filter has a rotating front element that is able to screw onto
the lens of your camera in order to reduce the glare that reflective
surfaces give off. The rotating front element is used to manage the
strength of polarization that the filter provides.
If the filter is turned one end, it will reveal what you would
normally see if the filter was not attached to it. This end is used to
essentially give you the same view you would see if it was not attached
so as not to increase the contrast of photographs you want to maintain.
When the polarizer is turned to about 90 degrees, most often the
reflections that you see through the viewfinder will disappear. This is
quite advantageous when shooting through glass panes where you would
normally see what is reflected by the glass instead of seeing what’s
behind it. This also applies to photographs where water is present.
Try taking a photograph of a fish in a pond without a polarizer and
then try taking a picture of the same subject with a polarizer on.
You’ll notice the difference because you would be able to see the fish
in the latter photograph with a circular polarizer on.
The visible reflections of trees and the sky are all cut out by the
circular polarizer and they also have a unique dramatic effect on blue
skies which give the effect of highly saturated colors. These types of
filters give the exceptionally blue skies that one would see in travel
brochures. It is through companies like Hoya that these types of filter
exist. Without them, our outdoor pictures would be dull, and lack the
necessary impact that they would have.
