Digital HT filters Digital HT filters are a state-of-the-art technological breakthrough in multi-coated photo & video filters. Made for the discerning professional & imaging enthusiast, Digital HT filters with Hi-Transa Double-Sided Titanium Multi-Coating surpass even military specifications for hardness & durability. Digital HT
- High Transmission
- filters offer the strength of a. Titanium coating combined with the purest optical quality glass & Tiffen&144;s Academy-Award-winning Color Core technology. They present unmatched scratch-resistant durability & 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). & that&144;s not all these High Transmission filters feature a low profile titanium finish ring & anti-reflective black lock ring which sets these filters apart from the rest. Digital HT Polarizing Filters Polarizers provide color & 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 & water. Color saturation in general, especially outdoors, can be enhanced significantly. Polarizer/ Circular Polarizer Essential general-use outdoor color filter Produces deeper skies & minimizes reflections in black & white & color photography Can be rotated to achieve desired effect A Circular Polarizer has the same effect as a. Polarizer & is used on cameras with beam splitting metering systems commonly found on auto focus SLRs (for most 3.5cm. 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&141;), rotate it around the axis of the index finger. It will point out the band of deepest blue from horizon to horizon.
