In photography and videography, a filter is a camera accessory consisting of an optical filter that can be inserted in the optical path. The filter can be a square or oblong shape mounted in a holder accessory, or, more commonly, a glass or plastic disk with a metal or plastic ring frame, which can be screwed in front of the lens or clipped onto the lens.Filters need to be coated to reduce flare, and this reduces (slightly) the amount of light that passes through the lens.Filters are (normally) fitted at the very front of a lens and because of this they ‘attract’ flare. Lenshoods are essential when filters are used, but there are many circumstances where a lenshood used without a filter will prevent flare but cannot prevent it when a filter is fitted. Filters allow the photographer to have more control of the images being produced. Sometimes they are used to make only subtle changes to images; other times the image would simply not be possible without them. Read the rest of this entry ».
