5. Hoya multi coated filters present the best value in filters available today Testing 1 2 3 Take a bare glass filter hold it so that light reflection off the surface can be seen Then take a long very thin object like a pin or the tip of a pen and hold it over the filter so that its reflection can be seen There will actually be two reflections of the pin on the surface one a little more pronounced than the other The more pronounced reflection Is from the front surface and the lighter one is from light reflecting off the rear surface Now try it with a HOYA Multi coated filter and see how much more dim the reflection is a dimmer reflection means less light is reflected off the surface of the glass multi coated 61 Reference data HOW TO SELECT COLOR FILTERS How to Select Color Conversion and Light Balancing Filters Each color film iE made 1o reproduce colors correctly when used with a speri ic fight source When other light sources are used color conversion filters must be used to match the color ol the light source to the film capabilities Light balancing fillers are used for slight adjustments of The color of the Bani source for cooler bluer or warmer redder tones Tha following table is gen for your convenience in selectlimg the proper filter To determine the necessary filler make a line from the original light source T1 to the converted light source T2 The proper filter will be indicated al ihe point whe

L 1 Over time the expansion and contraction of the different materials can lead to delamination which is a separation of the different materials This will show up as bubbling peeling or discoloration rendering the filter useless 2 The color of the gel can shift or fade over a relatively short period of time and will not yield the same color rendition 3 If all six surfaces three layers two surfaces each are not perfectly flat and perfectly parallel the filter causes a lens effect which degrades the optical performance or in extreme cases shift or limit the focus of the lens it is used with How Hoya Makes Filter Glass 1 L Not to scale Uniformly Colored Glass J To make it s filters Hoya adds different raw elements like gold and chemicals compounds to its optical glass silicates while mixing in a molten state To insure consistency in glass manufacturing Hoya uses a furnace called an Automatic V blender to mix the different materials continuously at a highly controlled rate This ensures that Hoya filter glass is uniformly colored all the way through There is never any risk of uneven coloration shifting or fading of the color or delamination The two surfaces are ground and polished for perfect flatness 58 NOT CREATED EQUAL M Hoya Coating and Multi Coating the Quality Difference Hoya manufactures a full line of filters in both standard and Hoya multi co
