The Formatt Hitech Firecrest ND 39mm ND 1.8 (6stops) Filter reduces the light reaching the camera by six stops. That gives you room to use a much longer exposure than the scene would otherwise allow. As a guide, a shutter speed of 1\/60 second becomes about one second with six stops of reduction, with aperture and ISO unchanged. It’s a practical option for photographers who want motion in a landscape or other static scene without changing the light itself. The 39mm designation identifies the filter size, so it’s important when choosing a filter to match a lens. This is a fixed-strength filter: its job is a substantial, specific reduction in light, rather than a variable adjustment.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eThe 39mm filter size is the key physical detail to get right: match it to a lens with a 39mm filter thread, and you can use the filter as intended. Its ND 1.8 rating means six stops of light reduction, which is enough to turn a bright-day 1\/60-second exposure into roughly one second without changing aperture or ISO. I’d use that sort of exposure for softening moving water or giving clouds visible movement; keep the framing steady while the shutter is open. This suits photographers who want a deliberate long-exposure effect. The trade-off is that six stops is a fixed amount, so it won’t offer the flexibility of changing the reduction.\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\u003eSeries: Firecrest\u003c\/li\u003e\n\u003cli\u003eFilter type: ND\u003c\/li\u003e\n\u003cli\u003eFilter size: 39mm\u003c\/li\u003e\n\u003cli\u003eND rating: 1.8\u003c\/li\u003e\n\u003cli\u003eLight reduction: 6 stops\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Formatt Hitech","offers":[{"title":"Default Title","offer_id":57563700330836,"sku":"FH-FC39ND1.8","price":65.08,"currency_code":"EUR","in_stock":false}],"url":"https:\/\/www.htf-store.com\/pl\/products\/formatt-hitech-firecrest-nd-39mm-nd-1-8-6stops-filter","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
