The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.\u003c\/p\u003e\n\n\n\n\u003cp\u003eA linear polarizer differs from a circular polarizer in that it does not contain an additional quarter wave plane. The addition of a quarter wave plane is to circularly polarize linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, in-camera auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.\u003c\/p\u003e\n\n\n\n\u003cp\u003eThis filter is recommended when not using in-camera exposure metering or autofocus. It is non-coated and delivers approximately 40% average light transmission.\u003c\/p\u003e\n\n\n\n\u003cp\u003eTiffen filters are made using ColorCore technology; a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1\/10,000th of an inch.\u003c\/p\u003e\n\n\u003c\/div\u003e\n\n\u003c\/div\u003e\n\n\u003c\/div\u003e\n\n\u003c\/div\u003e","brand":"Tiffen","offers":[{"title":"Default Title","offer_id":47123758350564,"sku":"TIF-45650POL","price":360.05,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0707\/4647\/2676\/files\/TIF-45650POL_bfe7db39-8190-46b8-b6c1-73001a222237.jpg?v=1764771205","url":"https:\/\/progear-website.myshopify.com\/products\/tiffen-4x5650-linear-polarizer-filter","provider":"Progear-website","version":"1.0","type":"link"}
