K\u0026amp;F Concept’s ND1000 is a very dark gray filter, rated at 10 stops, so it cuts incoming light and lets you choose a much longer shutter speed in bright conditions. That’s useful when you want moving water to blur or clouds to drift across the frame—effects that need time rather than a fast exposure. It suits landscape photographers and anyone planning a deliberate long exposure, as long as their setup accepts a 100 × 100 mm filter. The result still depends on the scene and the shutter time you choose; the filter doesn’t create motion by itself. Set your composition and decide how much movement you want before calculating the exposure.\u003c\/p\u003e\n\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eExposure planning becomes the main step once this dark filter is in place: I’d settle the composition and focus first, then work out the longer shutter time. Its 100 × 100 mm square format suits photographers already using a setup for filters of that size, while the ND1000 rating gives you a ten-stop reduction to include in your calculation. For a stream, a meter reading of 1\/1000 s without the filter becomes roughly 1 s with it, giving the water time to soften. That can also help clouds move across a landscape. I’d choose it when a pronounced long exposure is the goal. The same strong reduction is a limit if you want to keep shutter speeds fast.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: K\u0026amp;F Concept\u003c\/li\u003e\n\u003cli\u003eFilter size: 100 × 100 mm\u003c\/li\u003e\n\u003cli\u003eFilter type: ND1000\u003c\/li\u003e\n\u003cli\u003eFilter strength: 10 stop\u003c\/li\u003e\n\u003cli\u003eFilter color: Gray\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"K\u0026F Concept","offers":[{"title":"Default Title","offer_id":57492100514132,"sku":"KF-01.1410","price":56.71,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/2493\/3716\/files\/KF-01.1410_01.jpg?v=1791544448","url":"https:\/\/www.htf-store.com\/products\/k-f-concept-100x100-nd1000-filter-10-stop-gray-filter","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
