Improving Your Landscape Images...Part 2
Make your images more dramatic with a polarizing filter.
We use filters in photography to bring back an image to the way
our eyes have perceived the original scene. Some times it's not
possible for our cameras to record an exact scene - so we have
to rely on the manufacturers of camera products.
If you are only going to buy one filter for your landscape
photography a polarizing filter is the one you'll use most. A
polarizing filter can be used with colour or black and white and
is probably the most important filter on the market today.
Lets take a quick look at the science behind it. A polarizing
filter is made up of two pieces of glass which when rotated cut
out all glare on non-metallic surfaces. Light travels in waves -
these waves travel in all directions and at different rates and
speeds. The polarizing filter works by limiting the amount of
waves that enter your lens. You decide how many waves pass
through your lens by rotating the filter.
The polarizing filter is most effective with side lighting.
For example: if you are taking a picture of a scenic lake area
and there is a messy reflection of the clouds in the lake; it
will be too much of a distraction in the final picture. This can
be simply removed by rotating the polarizing filter 'til the
clouds disappear. You can view the filter working in the
viewfinder of your camera.
The polarizing filter will also darken the blue sky to give it a
strong rich colour. It will make mist stand out and can be also
used to give fast flowing water a misty effect.
You don't have to rotate the filter the full amount to get the
maximum affect you need, sometimes you will only have to rotate
it a small amount. You can decide best for yourself by viewing
through your viewfinder while you rotate the polarizing filter.
This filter is not just for a landscape photographer. There are
many different uses for a polarizing filter, which make it so
important for all photographers. Property photographers would
find this filter extremely handy - when taking an image of a
shop front, the polarizing filter will remove glare that
reflects off the glass.
Take extreme care when calculating exposure. Remember that you
will have to add two stops of light when using the polarizing.
