The Formatt Hitech Firecrest ND 100x100mm (4x4) ND 2.4 is a square neutral-density filter that reduces the light reaching your camera by 8 stops. It suits landscape photographers who want to show movement in a scene without waiting for dimmer conditions, and anyone exploring long exposures in daylight. Its 100 x 100 mm format makes it a defined square filter size to match with a suitable holder. The fixed ND 2.4 strength is most useful when you want a substantial shutter-time increase; it isn't a variable filter for adjusting density from one frame to the next. The result depends on your starting exposure and the movement in the scene, so use your meter reading as the starting point and choose a shutter speed that gives the subject the amount of blur you want.\u003c\/p\u003e\n\n\u003ch3\u003eWorking out your exposure\u003c\/h3\u003e\n\u003cp\u003eEight stops means multiplying the shutter time by 256. For example, a metered shutter speed of 1\/125 sec becomes roughly 2 sec with the filter in place. That gives moving water or passing clouds time to shift during the exposure, while stationary parts of the landscape remain recorded in place. Take a test frame and adjust from there: the right duration depends on how quickly the subject is moving and how much blur you want to show.\u003c\/p\u003e\n\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eAn eight-stop reduction makes multi-second daylight exposures possible without relying on an extremely small aperture just to slow the shutter. The 100 x 100 mm square format gives you a clear size to work around when choosing a holder, while the ND 2.4 strength removes enough light for a substantial exposure change. For a stream, start from your metered shutter time and multiply it by 256; 1\/125 sec becomes about 2 sec, a useful starting point for showing water movement. It also suits cloud movement across a landscape. Bear in mind that this is one fixed strength, so it may be more reduction than you want in some conditions.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFilter format: 100 x 100 mm (4x4)\u003c\/li\u003e\n\u003cli\u003eND density: ND 2.4\u003c\/li\u003e\n\u003cli\u003eLight reduction: 8 stops\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Formatt Hitech","offers":[{"title":"Default Title","offer_id":57492018364756,"sku":"FH-FC100ND2.4","price":112.13,"currency_code":"EUR","in_stock":true}],"url":"https:\/\/www.htf-store.com\/es\/products\/formatt-hitech-firecrest-nd-100x100mm-4x4-nd-2-4-8stops","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
