What's the Camera Lens Filters:

• Camera lens filters still have many uses in digital photography, and should be an important part of any photographer's camera bag. These can include polarizing filters to reduce glare and improve saturation, or simple UV/haze filters to provide extra protection for the front of your lens

Lens Filter Type:

• The most commonly used filters for digital photography include polarizing (linear/circular), UV/haze, neutral density, graduated neutral density and warming/cooling or color filters
• Example uses for each are listed below:

Problems with Lens Filters:

• Filters should only be used when necessary because they can also adversely affect the image. Since they effectively introduce an additional piece of glass between your camera's sensor and the subject, they have the potential to reduce image quality. This usually comes in the form of either a slight color tint, a reduction in local or overall image contrast, or ghosting and increased lens flare caused by light inadvertently reflecting off the inside of the filter
• Filters may also introduce physical vignetting (light fall-off or blackening at the edges of the image) if their opaque edge gets in the way of light entering the lens (right example). This was created by stacking a polarizing filter on top of a UV filter while also using a wide angle lens-causing the edges of the outermost filter to get in the way of the image. Stacking filters therefore has the potential to make all of the above problems much worse

Note on Choosing a Filter Size for a Camera Lens:

• Lens filters generally come in two varieties: screw-on and front filters. Front filters are more flexible because they can be used on virtually any lens diameter, however these may also be more cumbersome to use since they may need to be held in front of the lens. On the other hand, filter holder kits are available that can improve this process. Screw-on filters can provide an air-tight seal when needed for protection, and cannot accidentally move relative to the lens during composure. The main disadvantage is that a given screw-on filter will only work with a specific lens size
• The size of a screw-on filter is expressed in terms of its diameter, which corresponds to the diameter usually listed on the top or front of your camera lens. This diameter is listed in millimeters and usually ranges from about 46 to 82 mm for digital SLR cameras. Step-up or step-down adapters can enable a given filter size to be used on a lens with a smaller or larger diameter, respectively. However, step-down filter adapters may introduce substantial vignetting (since the filter may block light at the edges of the lens), whereas step-up adapters mean that your filter is much larger (and potentially more cumbersome) than is required
• The height of the filter edges may also be important. Ultra-thin and other special filters are designed so that they can be used on wide angle lenses without vignetting. On the other hand, these may also be much more expensive and often do not have threads on the outside to accept another filter (or sometimes even the lens cap)

How to Choose a Camera Lens Filter

Filters applied to your camera lens serve two main functions. First and foremost, they provide a protective barrier between your lens and the rest of the world. If the camera is ever dropped, the filter will take the brunt of the fall, often saving your valuable lens. Filters are also used for creative purposes in photography. They can alter the look of an image, assist in exposure and even help you photograph small objects close up.

• Determine what size of filter you will need. Look at the barrel of the lens which will have the filter attached. Look for a circle symbol with a line through it. This is the symbol that represents filter size. After the symbol will be a number. For example, 52mm after the symbol means you need to purchase a size 52mm filter.
• Shop for camera lens filters. Purchase filters at a local photography retailer, online or by mail order from photography magazine ads. Browse the variety of filters available, and determine which ones best suit your photography needs.
• Select a polarizing filter when photographing reflective objects. Choose a polarizing filter to help darken sky and saturate the color in your photos. They also help reduce glare on the surface of water or on glass display cases.
• Choose a sky or UV haze filter as a multipurpose filter. Choose this option to reduce haze viewed in long-distance photographs. If you are traveling and taking scenic photographs of landscape a long distance away, choose a sky or UV haze filter to help clarify the image. Select a sky or UV haze filter for general lens protection. It is best to always have a filter applied to your lens.
• Select black and white or sepia-toned filters to alter the look of your pictures. Shooting through these types of filters will change your photos from color to black and white or to a sepia brown tone. Once they are shot with these types of filters, you cannot go back to a color photo.
• Choose soft focus filters for a warm, diffused look. Soft focus filters are often used when photographing women, people with wrinkles or babies. Use a soft focus filter to also smooth out patchy skin tones and mild acne. These filters are also used in wedding portraits and senior portraits of females.
• Select magnifying filters for macro photography. Using these filters will allow you to take close-up pictures of small items. You can stack these types of filters to enhance the magnification.

How to Use a Polarizing Filter With a Camera Lens

Light travels in waves. When light strikes an object it is modified by the object. Light is absorbed by dark objects and reflected by objects like water, glass or rocks. To eliminate unwanted reflections in specular highlights, photographers use a filter on their camera lenses called a polarizing filter. This filter will allow you to control unwanted reflections from glass or water in your photographs. It can also be used to deepen the color of the sky or increase the differences between a cloud and the sky. It will remove glare from most views, but will have little impact on metal objects, which reflect mostly non-polarized light. The following are ways to use a polarizing filter with your camera lens.

• Screw the filter on to the front of the camera lens as you would any filter. You will notice this filter is different than most filters. It has an adjustment rim on the front of the filter. View your subject through the camera. In single lens reflect cameras you will be able to see the changes in the view finder immediately.
• Take a number of exposures adjusting the filter between each exposure. This will allow you to view prints or see screen images to determine the impact of the filter.
• Notice the change in sky and the appearance of the rocks. Try taking pictures through a window and use the filter to minimize the glass reflections.

Tips & Warnings

• Use the filter for scenes with a lot of sky or water. Observe the changes as you turn the filter.
• You can do a lot of things in Photoshop, but removing unwanted reflections is difficult.
• It is definitely worth having this inexpensive tool in your camera bag.
• You can use a polarizing film with a non SLR camera, but you will only be able to see the changes in your exposures, not through the viewfinder.
