ND filters are among those tools which have become indispensable in today's digital technology. They offer the possibility to achieve otherwise unachievable results as they are the real sunglasses for your camera. Typically, ND filters are used when shooting in bright light such as strong sunshine, snowy mountains or on white beaches. ND's filter the entire visible spectrum evenly, allowing light reduction - reducing the amount of light reaching the CCD, film or tape, without altering the relative spectral distribution of the energy, thus without influence on colour temperature, colour balance or contrast. For this reason they are often referred to as neutral or grey filters.
