The Tiffen HT 58mm Circular Polarising Hi-Trans Double sided Titanium Multi coated filter provides colour and contrast enhancement.
Reflected light often shows up as whitish glare that washes out colour in an image.
A Polariser corrects this problem producing deep, dramatically blue skies.
It also removes glare from non-metallic surfaces, such as windows and water.
Colour saturation in general, especially outdoors, can be improved significantly.
