The filter absorbs blue\ncolors, rendering blues darker. Haze is minimized for aerial photography and\nexcessive blue is removed for astrophotography. The 12 Yellow Filter is\nrecommended as a basic filter for use with Kodak's Aero Ektachrome Infrared\nFilm. The filter has a filter factor of 2, so you must increase by 1 full stop\nto your exposure to compensate. Tiffen filters are not dyed, but are\nmanufactured by using ColorCore technology. This process laminates the filter\nmaterial between two pieces of optical glass and grinds down and polishes the\nglass. The glass is then mounted to the metal ring, which after that can be\nscrewed onto the lens for the desired effect.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eReduces excess blue of full moon in astrophotography\u003c\/li\u003e\n         \u003cli\u003e\"Minus blue\" cuts haze in aerial work\u003c\/li\u003e\n         \u003cli\u003ePrimarily for black-and-white images\u003c\/li\u003e\n         \u003cli\u003e67mm diameter\u003c\/li\u003e\n  \u003c\/ul\u003e","brand":"Tiffen","offers":[{"title":"Filter \/ 67mm","offer_id":44381988257972,"sku":"B00004ZCGF","price":215.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9906\/1172\/files\/B00004ZCGF.jpg?v=1789140007","url":"https:\/\/auspowers.com\/products\/tiffen-67mm-yellow-12-camera-lens-filter-for-black-white-photography","provider":"AusPower Australia","version":"1.0","type":"link"}
