TELESIN ND 8 16 32 Filters Kit is an essential accessory for any photographer's camera bag. It reduces the amount of visible light that enters the lens, allowing the user to utilize wider apertures or slower shutter speeds, particularly in bright conditions. It works especially well for portraits by allowing the photographer to reduce the depth of field, producing pleasant background blur while keeping the subject in sharp focus.These filters are also often used to emphasize movement by permitting slow shutter speeds in bright light, giving life to photos that would otherwise look frozen in time. ND 8 filter (4 Grams) - This filter is helpful for reducing light from entering the lens by 3 f-stops, which is best for photography in partial cloudy daytime conditions. This filter also helps to reduce the lens flare from the sun effectively to give crystal-clear images. ND 16 filter (4 Grams) - This filter is used to cut light entering the lens by 4 f-stops, which makes it best-suited for filming in normal sunny conditions. This filter is helpful to get natural-looking blur in the footage while filming outdoors. ND 32 filter (4 Grams) - This filter is helpful in reducing the amount of light from falling on the sensor by 5 f-stops, making it an ideal choice of filter for filming in bright sunny conditions. Apart from this the filter effectively prevents lens flare from spoiling the picture while filming against the sun. This helps to tone down the highlights of the sky and get a sharp image of the landscape.
