Warming filters are designated by the
numbers 81 and 85, while cooling filters are designated by the
numbers 80 and 82. Warming filters add an orange tint to an image,
and cooling filters add a blue tint to an image.
Neutral density Reduces the amount of light reaching the image sensor. Use a
neutral-density filter when you want to photograph a scene using
a wider aperture (low f-stop number) or a slower shutter speed.
Popular neutral-density filters are ND2X (which reduces exposure
by one f-stop) and ND4X (which reduces exposure by two f-stops).
Polarizing Reduces glare from reflective surfaces. Polarizing filters also
increase the saturation of the sky, which makes it look bluer and
provides good contrast with clouds in the scene.
Skylight Used to reduce the bluish cast that often appears in images
photographed in daylight. This filter adds warmth to an image.
Special effects A wide variety of special effects filters are available. For example,
you can purchase filters that will split a scene into multiple images,
add lighting effects such as starbursts, and so on. Visit a camera
shop or online camera store to find out more about special effects
filters.
Ultraviolet Filters out ultraviolet rays, which can reduce haze when photographing
scenes with distant details.
