The Cokin A123F Gradual Blue B2-FULL is for photographers who want more blue in a sky while keeping the rest of the scene more natural. It’s especially suited to landscapes and views with a clear division between sky and foreground, where you can position the blue area over the sky. The name identifies this as the B2-FULL version of Cokin’s A123F gradual blue filter. That makes it a specific option for photographers who want this effect, rather than a general colour filter. Keep the horizon or other transition in mind as you compose: the result depends on where the gradual area falls in the frame.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eA pale sky above a dark ridge is exactly the sort of scene where the A123F earns its place: the blue treatment can bring more colour to the sky without putting the same blue over the whole composition. I’d consider it for landscape views with a clean horizon, or a city skyline against open sky. Compose so the transition sits around that boundary, then check that it doesn’t cut through an important subject. The B2-FULL designation is useful when you’re choosing this particular version by name; the filter’s gradual-blue character is the reason to reach for it. It won’t suit every frame—busy scenes with no clear division can make the transition harder to place.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Cokin\u003c\/li\u003e\n\u003cli\u003eProduct type: Filter\u003c\/li\u003e\n\u003cli\u003eFilter effect: Gradual Blue\u003c\/li\u003e\n\u003cli\u003eModel: A123F\u003c\/li\u003e\n\u003cli\u003eDesignation: B2-FULL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Cokin","offers":[{"title":"Default Title","offer_id":57503287509332,"sku":"D110102","price":16.33,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/2493\/3716\/files\/D110102_01.jpg?v=1791566160","url":"https:\/\/www.htf-store.com\/ar\/products\/cokin-filter-a123f-gradual-blue-b2-full","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
