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:

Linear & Circular Polarizing Filters:

• Polarizing filters (aka "polarizers") are perhaps the most important of any filter for landscape photography. They work by reducing the amount of reflected light that passes to your camera's sensor. Similar to polarizing sunglasses, polarizers will make skies appear deeper blue, will reduce glare and reflections off of water and other surfaces, and will reduce the contrast between land and sky

• Note how the sky becomes a much darker blue, and how the foliage/rocks acquire slightly more color saturation. The intensity of the polarizing effect can be varied by slowly rotating your polarizing filter, although no more than 180° of rotation is needed, since beyond this the possible intensities repeat. Use your camera's viewfinder (or rear LCD screen) to view the effect as you rotate the polarizing filter.The polarizing effect may also increase or decrease substantially depending on the direction your camera is pointed and the position of the sun in the sky. The effect is strongest when your camera is aimed in a direction which is perpendicular to the direction of the sun's incoming light. This means that if the sun is directly overhead, the polarizing effect will be greatest near the horizon in all directions
• However, polarizing filters should be used with caution because they may adversely affect the photo. Polarizers dramatically reduce the amount of light reaching the camera's sensor-often by 2-3 f-stops (1/4 to 1/8 the amount of light). This means that the risk of a blurred handheld image goes up dramatically, and may make some action shots prohibitive
• Additionally, using a polarizer on a wide angle lens can produce an uneven or unrealistic looking sky which visibly darkens. In the example to the left, the sky could be considered unusually uneven and too dark at the top 

• Linear vs. Circular Polarizing Filters: The circular polarizing variety is designed so that the camera's metering and autofocus systems can still function. Linear polarizers are much less expensive, but cannot be used with cameras that have through-the-lens (TTL) metering and autofocus-meaning nearly all digital SLR cameras. One could of course forego metering and autofocus, but that is rarely desirable

Neutral Density Filters:

• Neutral density (ND) filters uniformly reduce the amount of light reaching the camera's sensor. This is useful when a sufficiently long exposure time is not otherwise attainable within a given range of possible apertures (at the lowest ISO setting)

Usage:

• Smoothing water movement in waterfalls, rivers, oceans, etc.
• Achieving a shallower depth of field in very bright light
• Reducing diffraction (which reduces sharpness) by enabling a larger aperture
• Making moving objects less apparent or not visible (such as people or cars)
• Introducing blur to convey motion with moving subjects
• photo with a smoothed water effect from a long exposure
• However, only use ND filters when absolutely necessary because they effectively discard light-which could otherwise be used to enable a shorter shutter speed (to freeze action), a smaller aperture (for depth of field) or a lower ISO setting (to reduce image noise). Additionally, some ND filters can add a very slight color cast to the image.
• Generally no more than a few f-stops is need for most waterfall scenarios, so most photographers just keep one or two different ND filter amounts on hand. Extreme light reduction can enable very long exposures even during broad daylight

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

Guide to Select Camera Lens Filter:

• 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
• 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
