Photo Filters - What They Are, and How They're Used

A photo filter is basically a camera accessory which allows the photographer to better control the outcome of their photos. Some filters create only subtle effects while others can completely change the way a photo looks. The downside to using filters is that if the filter is scratched or dirty, it will reflect on the image. So if you are going to be using filters on your camera, make sure they are always clean and free from scratches.

There are numerous types of photo filters available:

-Clear Filters are completely transparent and do not affect the outcome of the photo. They are mainly used to protect the camera lens.

-UV Filters are used to reduce the haze caused by certain types of light

-Color Correction filters are used to better balance the colors that are captured in photos. These are not as common since digital photography has become popular, since digital cameras generally balance colors automatically within the camera itself.

-Color Subtraction filters are used to block a certain color from a photo, but leaving the rest of the colors intact

-Contrast Enhancement filters are normally used in black and white photography to adjust the contrast of the photo. For instance, if you were taking a photo of the sky in black and white and you wanted to enhance contrast, you may use a yellow or orange filter which would brighten the clouds, and cause the sky behind them to seem darker.

-Polarizing filters can be used to darken skies that are too bright, and can even reduce reflected sunlight. These filters are also used to minimize reflections such as those from windows.

-Neutral Density filters are commonly used to reduce light. This is particularly handy when using longer exposure times.

-Diffusion Filters are used to give a softer appearance of a photo and are often used in portraits.

Filters are usually made from glass, resin, polyester, polycarbonate, and sometimes acetate. They come in all sizes and varieties, only a few of which I described above. Using filters can add a lot of variety to your photography, and create some effects that would not otherwise be possible.
