It suits photographers who want to show movement in a scene rather than freeze every detail: think flowing water rendered with a softer look, or clouds that shift across a landscape during a longer exposure. The filter can also help when you want to use a wider aperture in strong light, though the result depends on your lens and the available light. Its particular strength is that substantial reduction in incoming light, which opens up shutter-speed choices that may otherwise be impractical in daylight. If you enjoy making deliberate exposure choices and working with motion, this is a straightforward tool to consider.\u003c\/p\u003e\n\u003ch3\u003ePutting seven stops to work\u003c\/h3\u003e\n\u003cp\u003eSeven stops is a significant change, so plan your exposure around the light reduction. As a simple example, a shutter speed of 1\/125 second without the filter becomes approximately one second with it, assuming the same aperture and ISO. That can turn moving water into a smoother-looking surface while leaving fixed parts of the scene sharp, provided your camera is steady. For a more restrained effect, choose a faster starting shutter speed or adjust the exposure settings; the filter’s strength stays the same.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eSeven stops takes a 1\/125-second exposure to about one second, which gives moving water time to soften instead of appearing frozen. I’d suggest this filter to someone who wants that slower-shutter look in daylight, especially for a waterfall or a stream; start with the exposure you’d use without the filter, then compensate for the seven-stop reduction. The 67mm size is the other detail to pay attention to: it needs to match the filter diameter of the lens you plan to use. ND 2.1 is a strong reduction, so it’s less suited to subtle changes in shutter speed. For more modest light control, you’d want a lighter ND strength.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Formatt Hitech\u003c\/li\u003e\n\u003cli\u003eFilter size: 67mm\u003c\/li\u003e\n\u003cli\u003eND density: 2.1\u003c\/li\u003e\n\u003cli\u003eLight reduction: 7 stops\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Formatt Hitech","offers":[{"title":"Default Title","offer_id":57503370903892,"sku":"FH-FC67CIRCND2.1","price":77.43,"currency_code":"EUR","in_stock":true}],"url":"https:\/\/www.htf-store.com\/zh\/products\/formatt-hitech-firecrest-nd-67mm-nd-2-1-7stops-filter","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
