Hoya 77 mm Colour Filter HMC 82B for Lens

Color Filter HMC 82B 77mm. In conditions of extreme light intensity, such as sunshine on snowy mountains or on the beach, or when using a camcorder, ND (Neutral Density) filters are recommended as essential. Neutral Density filters are often ignored by photographers, but they have several uses and offer the possibility to achieve otherwise unachievable results. ND filters appear grey and reduce the amount of light reaching the film, they have no affect on color balance. They have four main uses: 1) To enable slow shutter speeds to be used, especially with fast films, to record movement in subjects such as waterfalls, clouds, cars, seas etc. 2) To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background. 3) To decrease the effective ISO of high speed film (ie: above ISO400) and allow it to be used outdoors in blight situations. 4) To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which would normally cause over-exposure.

• These are light balancing filters used to increase the color temperature slightly for a cooler (bluer) tone
• Corrects the tendency toward reddish tones
• These series filters are also used to prevent the reddish tones in early morning or late evening light for natural skin tones
