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 newwer slpit-beam metering systems used in auto focus cameras. Check your camera's manual.

Bought this linear filter to stack on top of my circular polarizer to cut down on bright midday light while shooting moving water from fountains. It takes a few moments to line up the filters, but once you do .... you get a flowy water image, shot at slow speed, which would have otherwise, been impossible. Works even better with a tripod, but for travel... a small and portable solution for sure. Both filters I use are hoyas, and filter compatibility counts.
