This medium yellow filter slightly darkens skies, helps to cut through haze, and improves overall contrast. It is the most common contrast filter for black and white photography, producing an accurate tonal range and compensating for the blue sensitivity of panchromatic film. There is a 2x filter factor with this filter, requiring an increase of 1 stop for normal exposure. The front and rear surfaces of the filter both feature a single anti-reflection coating. Each coating helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, they offer protection to the filter substrate while helping to keep the glass clean for longer than uncoated glass.\u003c\/span\u003e  \u003c\/p\u003e            \u003c\/div\u003e\u003cp\u003e\u003cstrong\u003eProduct Information\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\u003ctable style=\"margin-bottom:20px\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProduct Dimensions\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e0.9 x 2.6 x 3.5 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eItem Weight\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e1.92 ounces\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eASIN\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eB0000BZLMF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eItem model number\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e703903\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCustomer Reviews\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBest Sellers Rank\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDate First Available\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eJune 17, 2003\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eHeliopan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003c\/ul\u003e","brand":"Heliopan","offers":[{"title":"Default Title","offer_id":52759410278718,"sku":"703903","price":77.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0969\/3560\/8638\/files\/yellow_8.webp?v=1767042472","url":"https:\/\/heliopanusa.com\/products\/39mm-medium-yellow-filter-703903","provider":"Heliopan","version":"1.0","type":"link"}
