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? 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
* Combine a Polarizer with a Red 25 for incredibly dramatic black and white landscapes
* Can be rotated to achieve desired effect
* Use the Tiffen Polarizer with the enhancing filter for more dramatic effects
* Available for Wide Angle lenses
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.
