Polarizers provide color and contrast enhancement. Reflected light often shows up as whitish glare that washes out color in an image. A Polarizer corrects this problem producing deep, dramatically blue skies. It also removes glare from non-metallic surfaces, such as windows and water. Color saturation in general, especially outdoors, can be improved significantly.
Often, you want to balance light intensity between two areas within a scene. This is important outdoors to allow more sky detail while properly exposing the foreground. Exposing for the foreground will produce a washed-out, over-exposed sky, exposing for the sky will leave the foreground dark, underexposed.
These filters reduce the amount of light passing through the camera lens without changing the color of the scene. They are especially useful in bright light conditions to help prevent overexposure. Neutral Density filters also allow proper exposure at a wider lens opening for reduced depth-of-field to highlight a key subject by making the foreground and/or background out of focus.
Designed to take extreme long exposure photographs in a manual set up, the AXENT filter will allow you to blur the movement in your image. The intensity of this effect is achieved by manually setting up your camera and is a combination of aperture, shutter and ISO settings. When your DSLR is set in color mode, the filter will allow through some IR light waves. The effect of IR absorption onto your sensor will depend on the lighting conditions and will gently to radically affect your image color.
It is easy to see why the Black Pro-Mists have been such a success for over the past 30 or so years. Its unique layering of contrast combined with a gauzy paint like halation, function as a twist on the stand of the pro halation spill effect. Even at its lowest density, it delivers an effective and increase in the halation which adds a pleasing depth of warmth, but is not transported to the skin tone values. These characteristics will become more apparent when you use densities of 1 quarter and above.
A Circular Polarizer has the same effect as a Polarizer and is used on cameras with beam splitting metering systems commonly found on auto focus SLR's (for most 35mm auto-focus cameras see your camera manual).
