Hoya manufactures a full line of filters in both standard and Hoya multi coated The difference between Hoya s standard line and that of other manufacturer is that Hoya standard filters have a layer of anti reflective coating bonded to each surface of the glass Many other manufacturer s standard filters are bare glass and bare glass can reflect as much as 10 of the light hitting it This greatly increases the risks of flare and ghosting and reflections m o 4 5 Total of 9 4 59 Light Ray po Hoya s single layer coating decreases light reflection off the surface from approx 10 down to 4 5 Multi Coating Clearly Different r 2 to 2 5 Total of 4 to 556 Light Ray 2 to 2 5 Single Layer coating To provide photographers with a higher quality professionals require Hoya created the Multi coated line of filters These filters have a 3 layer coating system that further reduces light reflections off the surfaces of the glass the average is only 1 2 This means that 98 99 of the light striking the filter is going through it into the camera lens and onto the film or sensor These layers of anti reflective coating are bonded to the surface of the glass in a furnace at a temperature of up to 800 degrees F so there is never any chance of the coatings coming off through normal use E Light Ray 1 to 2 You should beware Some other manufacturers claim to have coated filters But this coating

Digital GENERAL FILTERS PL PL CIR Color and contrast enhancement With PL Filter ch AA ar A Without Filter What is a polarizing filter Light rays which are reflected by any surface can become polarised so polarising filters are used to select which light rays enter your camera lens CIRCULAR PL filters allow you to remove unwanted reflections from non metallic surfaces such as water glass etc They also enable colors to become more saturated and appear clearer with better contrast This effect is often used to increase the contrast and saturation in blue skies and white clouds HOYA s polarising filters will not affect the overall color balance of a shot 28 GENERAL FILTERS for Film amp Digital How to select the correct Polarizing Filter Two kinds of polarizing filters are the PL Linear Polarizing and PL CIR Circular Polarizing filters which have the same effect of reducing glare however there are differences in the way each works in combination with your specific camera so it is important to research and choose the correct version of filter for your camera Many of today s cameras use semi silvered mirrors or prisms to split the light a k a beam entering the viewfinder in order to calculate exposure and focusing distance PL filters can sometimes interact with these light controlling devices to give unpredictable exposure or focusing If your camera whether auto or manual is equipped with
