Light rays which are reflected by any surface become polarised and polarising filters are used to select which light rays enter your camara lens.
• They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc.
• They also saturate colors and increase contrast.
• Polarizers come in two variations but have the same effect. Linear polarizers work with older camera meters; Circurlar polarizers are designed for today's newer split-beam metering systems used in auto focus cameras. Check your camera's manual.
Tiffen Digital HT® Filters
Made from the purest optical quality glass and Tiffen's award-winning ColorCore technology, Tiffen Digital HT - High Transmission - filters offer a new breakthrough in multi-coating technology.
Imagine, a double-sided coated filter with the strength of titanium, unmatched scratch-resistant durability and worry-free cleaning.
Other coated filters on the market today cautiously suggest delicate, if any, cleaning procedures, in fear of destroying the coating (and thereby the filter).
Not with the Digital HT filters - the secret is in the titanium coating that makes it extremely durable and protects against damage and mark up.
And that's not all these High Transmission filters feature a low profile titanium finish ring and anti-reflective black lock ring, with a distinctive titanium finish that sets these filters apart from the rest. Digital HT filters are made in the USA and come with a 10-year warranty your guarantee of quality assurance.
Digital HT filters are available as the following filters: Digital Ultra Clear, Haze 86 (with 86% UV absorption), Circular Polarizer, 812® Warming Filter, ND .06, ND 1.2, Soft/FX® 3, Star 4 Point 2, and Color-Grad® ND.0.6 in sizes 52mm-82mm.
