It’s for landscape and outdoor photographers who want to manage exposure while keeping their chosen aperture and ISO. With less light reaching the camera, you can use a slower shutter speed to show movement in flowing water or passing clouds, or open the aperture when the light is bright. For example, if your starting exposure is 1\/30 sec, two stops less light lets you use about 1\/8 sec at the same aperture and ISO. The square format suits photographers working with a compatible square-filter holder, rather than a round screw-in filter setup. Its most useful role is modest, deliberate exposure adjustment: enough to make motion more visible or give you room to change settings, without turning a daytime scene into an extremely long exposure. It’s a straightforward option when that two-stop reduction is what your shot calls for.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eLandscape photographers working with streams, waterfalls or moving cloud will get the clearest use from this filter. The 100 × 100 mm square format means you can position it in a holder made for that size, which is handy when you want to control where the filter sits in front of the lens. Its ND4 strength takes away two stops: if your meter gives 1\/30 sec, try 1\/8 sec at the same aperture and ISO to bring some motion into the water. I’d also consider it when you need a little more room to open the aperture outdoors. One honest limit: two stops won’t create very long exposures in bright daylight; choose it for measured adjustments, not dramatic blur.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProduct type: ND filter\u003c\/li\u003e\n\u003cli\u003eFilter size: 100 × 100 mm\u003c\/li\u003e\n\u003cli\u003eFilter strength: ND4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"K\u0026F Concept","offers":[{"title":"Default Title","offer_id":57563807646036,"sku":"KF-01.1839","price":54.1,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/2493\/3716\/files\/KF-01.1839_01.jpg?v=1791805170","url":"https:\/\/www.htf-store.com\/de\/products\/k-f-concept-100x100-nd4-filter","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
