Digital HT Polarizing Filters Polarizers provide color and contrast enhancement. Reflected light often shows up as whitish glare that washes out color in an image. A Polarizer corrects this problem producing deep, dramatically blue skies. It also removes glare from non-metallic surfaces, such as windows and water. Color saturation in general, especially outdoors, can be improved significantly.
Essential general-use outdoor color filter
Produces deeper skies and minimizes reflections in black and white and color photography
Can be rotated to achieve desired effect
A Circular Polarizer has the same effect as a Polarizer and is used on cameras with beam splitting metering systems commonly found on auto focus SLR's (for most 35mm auto-focus cameras see your camera manual).
Area of sky most effectively polarized with a Circular Polarizer:
Point your index finger at the sun. With your thumb extended at a right angle (90°), rotate it around the axis of the index finger. It will point out the band of deepest blue from horizon to horizon.
Digital HT Filters Digital HT filters are a state-of-the-art technological breakthrough in multi-coated photo and video filters. Made for the discerning professional and imaging enthusiast, Digital HT filters with Hi-Trans® Double-Sided Titanium Multi-Coating surpass even military specifications for hardness and durability.*
Digital HT - High Transmission - filters offer the strength of a Titanium coating combined with the purest optical quality glass and Tiffen's Academy-Award-winning ColorCore technology. They present unmatched scratch-resistant durability and worry-free cleaning while other coated filters on the market today cautiously suggest delicate, if any, cleaning procedures, in fear of destroying the coating (and thereby the filter).
And that's not all - these High Transmission filters feature a low profile titanium finish ring and anti-reflective black lock ring which 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: Digital Ultra Clear, Haze 86 (with 86% UV absorption), Circular Polarizer, 812® Warming Filter, ND 0.6, ND 1.2, Soft/FX® 3, Star 4 Point 2, and Color-Grad® ND 0.6 in sizes 52mm-82mm. Each filter comes with its own distinctive soft pouch for storage when not in use.
Tiffen's research and development team has conquered the challenges of multi-coating. No longer is your investment in a multi-coated filter subject to the everyday challenges of dirt, humidity, and potential scratching which can render your multi-coated filter useless.
Along with the extreme toughness and durability, Tiffen Digital HT Titanium Coating features excellent Anti-Reflective and Transmission (HT Ã¢ High Transmission) characteristics. The Titanium coating consistently reflects less than 1% of the imaging light hitting the front surface of the filter while transmitting nearly 99%.
