Violet Filter
Posted on Tuesday, October 13, 2009 in Photography
how do ultra violet filters work?
Light is a whole range of frequencies as I expect you know from infra red to ultra violet. Adding specific chemicals to glass or a coating on the glass can make it appear coloured by absorbing some light frequencies. UV filters are just geared up to absorbing the specific frequencies of UV light which otherwise causes some strange and often undesirable effects in photography or in the case of sunglasses, you look to absorb UVA and/or UVB to protect your eyes from this harmful radiation.
