The Tiffen 44ND18 is a neutral density filter with a 1.8 density, reducing the light reaching the camera while leaving you in control of your chosen aperture and shutter speed. That makes it useful when a scene is brighter than the exposure you want: you can use a slower shutter to show movement, or keep a wider aperture for a shallower depth of field. A 1.8 density corresponds to six stops of light reduction, a substantial cut that’s especially helpful outdoors in daylight. It suits landscape and motion-focused work where you want to manage exposure without changing the look you’re aiming for. The key practical point is to use a filter system that accepts the 4x4 format; the filter’s size is central to choosing the right setup.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eFor photographers shaping moving water, passing clouds or daylight portraits, this filter gives you a clear amount of exposure control to work with. Its 1.8 density cuts six stops, so, for example, a 1\/60 sec exposure can become roughly one second at the same aperture and ISO; that’s enough to soften flowing water, provided the light and scene stay consistent. The 4x4 format means your holder needs to accept that size, so I’d make that the first practical check when planning a setup. It’s also useful for keeping a wider aperture outdoors without pushing the shutter speed beyond what you want. Just bear in mind that six stops won’t suit every bright-light long exposure: the result still depends on the conditions and your starting exposure.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Tiffen\u003c\/li\u003e\n\u003cli\u003eFilter type: Neutral density\u003c\/li\u003e\n\u003cli\u003eFormat: 4x4\u003c\/li\u003e\n\u003cli\u003eDensity: 1.8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tiffen","offers":[{"title":"Default Title","offer_id":57564046328148,"sku":"44ND18","price":215.49,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/2493\/3716\/files\/44ND18_01.jpg?v=1791805517","url":"https:\/\/www.htf-store.com\/fr\/products\/tiffen-44nd18-4x4-neutral-density-1-8-filter","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
