They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also enable colors to become more saturated and appear clearer, with better contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds.\u003c\/p\u003e\u003cp\u003ePolarizers do not affect the overall color balance of a shot. It is important that you choose the correct version of polarizer for your camera. Many of today's cameras use semi-silvered mirrors or prisms to split the light entering the viewfinder in order to calculate exposure and focusing distance. Polarizing filters can sometimes interact with these items to give unpredictable exposure or focusing.\u003c\/p\u003e\u003cp\u003eIt is recommended that you choose a circular polarizer such as this one from Promaster unless you have a manual focus camera which has no beam splitter. If you will be using your Polarizing filter on a lens which has a focal length of 28mm or wider (on a 35mm camera), we recommend that you use a Wide Circular Polarizer to avoid a possible vignette effect. \u003c\/p\u003e","brand":"ProMaster","offers":[{"title":"Default Title","offer_id":46926911635631,"sku":"29144017934","price":59.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6415\/2239\/files\/029144017934_0.jpg?v=1779085092","url":"https:\/\/freshized.com\/products\/promaster-1793-40-5mm-circular-polarizing-filter-digital-coated","provider":"Freshized","version":"1.0","type":"link"}
