Offering greater tonal separation\nthan regular yellow and orange contrast filters, the light-red 23A is\nespecially well-suited to producing dramatic outdoor and landscape imagery.\nThere is an approximate 4x filter factor with this filter, requiring an\nincrease of 2 stops for normal exposure.The filter is constructed using\nTiffen's ColorCore technology, which involves lamenting the filter material\nbetween two pieces of optical glass, grounding flat to a tolerance of\n1\/10,000th of an inch, and mounting within an aluminum alloy ring.Light-red\nfilter provides the same effect as a Wratten 23A contrast filter, and helps to\ndarken blue tones while lightening warm orange and red tones, when\nphotographing in black and white.Commonly used for landscape photography to\nemphasize and darken blue skies and give clouds more visual depth.Filter\nfactor of 4 requires approximately 2 stops of additional exposure to maintain\nnormal results.ColorCore technology, which permanently laminates the filter\nmaterial between two pieces of optical glass, maintains image clarity,\naccuracy, and consistency.Aluminum filter ring is both lightweight and\ndurable.Increases Black and White ContrastEffect Corresponds to Wratten 23A\nFilterDarkens Blue TonesLightens Red and Orange Tones  Not\nrecommended for flesh tones.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eLight red filter\u003c\/li\u003e\n         \u003cli\u003eProduces contrast effects that darken sky and water\u003c\/li\u003e\n         \u003cli\u003e58mm diameter\u003c\/li\u003e\n         \u003cli\u003ePrimarily for black-and-white images\u003c\/li\u003e\n  \u003c\/ul\u003e\n","brand":"Tiffen","offers":[{"title":"Default Title","offer_id":42173356245145,"sku":"B00004ZCDM","price":171.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0491\/3148\/7385\/products\/B00004ZCDM.jpg?v=1653576944","url":"https:\/\/soundstores.net\/products\/tiffen-58mm-23a-filter-red","provider":"SoundStore Australia","version":"1.0","type":"link"}
