It suits photographers and filmmakers whose filter setup accepts a 112mm filter and who need a substantial reduction in light, rather than a mild adjustment. A 1.8 optical density corresponds to six stops, which can make a practical difference in strong daylight: you can use a slower shutter speed or a wider aperture without changing the scene’s lighting. That’s especially useful when you want motion blur in a bright setting or need more control over exposure. The main thing to plan around is the 112mm format; this is for a setup built to accept that size, not a smaller filter thread.\u003c\/p\u003e\n\n\u003ch3\u003eWorking with six stops of reduction\u003c\/h3\u003e\n\u003cp\u003eA six-stop ND filter changes exposure by a predictable amount: a shutter speed of 1\/60 sec becomes about 1 sec if aperture and ISO stay the same. That gives you a starting point for planning a long exposure in daylight. For video, the same light reduction can help keep a chosen shutter speed when the scene is bright. The IRND name identifies this as more than a plain ND designation, but the title alone doesn’t give a specific transmission or colour-performance figure to plan around.\u003c\/p\u003e\n\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003e1.8 means six stops of light reduction in practice, enough to turn a 1\/60 sec exposure into about 1 sec at the same aperture and ISO. I’d suggest that kind of starting point for a daylight long exposure where you want moving water to blur. The 112mm size matters just as much in planning: your filter holder or matte-box setup needs to accept that diameter. This suits filmmakers and still photographers working with a large-format filter setup who need a strong ND reduction. One honest point: six stops can be too much when light is already low, so this is best saved for bright conditions.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Tokina\u003c\/li\u003e\n\u003cli\u003eFilter size: 112mm\u003c\/li\u003e\n\u003cli\u003eType: Pro IRND 1.8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tokina","offers":[{"title":"Default Title","offer_id":57503625249108,"sku":"TO-CIRND18P112","price":140.62,"currency_code":"EUR","in_stock":true}],"url":"https:\/\/www.htf-store.com\/zh\/products\/tokina-112mm-pro-irnd-1-8","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
