Digital Camera Basics - Making Use Of A Polarizing Filter

By Dan Feildman




Digital camera basics, tips and tricks to turn you into a much better digital photographer, simply by learning how your camera works.

A polarizing filter is one of the most useful filters you can own. In my opinion, it needs to be the very first filter you get. These filters function by reducing the glare that shows up on countless objects. This includes glare coming from tiny water droplets in the atmosphere that may distort the color of the sky.

If the glare on objects becomes reduced it results in a lot more color saturation and more contrast within the picture. You'll find that the sky seems bluer and leaves appear greener. It is also perfect for taking photos of water because it reduces the amount of reflection you'll get on the surface enabling you to see the specifics within the water. These effects make this filter popular for landscaping photography.

Here's a much better outline regarding what a polarizing filter will do.

Water - The filter can get rid of glare to make the water look more transparent. You'll be able to photograph specifics underneath the surface of clear water and you will be able to secure the specifics on the surface of really murky water. To get water to appear the most transparent photograph from above aiming down into the body of water.

Glass - If you have ever tried to shoot a photo through glass you are aware how complicated it can be. The glare coming from the glass always shows up in your photo. If you utilize a filter you get rid of any glare creating a translucent surface to shoot through.

Sky - Tiny droplets of water within the environment reflect light producing glare on your photos. When you eliminate that glare you get skies which are a much more intense blue. Such filters are ideal for avoiding white overexposed skies. This is best suited when the sun is in a 90 degree angle to your filter.

Colors - These kinds of filters will amp up the colors on your pictures by eliminating the glare that typically lightens colors. It will be particularly apparent on vegetation.

Polarizing filters screw into the face of your lens. Spherical filters are most frequently used and can be adjusted by turning them. As you turn the front component of your filter the colors will change within the image. You are able to adjust the filter to get the result you're looking for prior to taking the image. These kinds of filters are very dense and really should not be used with lenses wider than 28mm. On larger angle lenses the perimeters of the filter will distort the edges of the photo giving you a vignetting effect. You can purchase finer filters, however these are usually expensive.

It's also wise to avoid using these filters for taking panoramic photos since you will end up having different color properties within the pictures that will make it tough to piece the pictures together into a continuous picture. These kinds of filters will be dark so you will need to adjust your exposure appropriately. Open your aperture wider or prolong the shutter time to allow the correct quantity of light to get on the sensing unit. You may need to use a tripod to keep your camera still. Refrain from using this filter for low light situations and on cloudy days. These filters are rather dark and can simply make your photos too dark in these conditions.
