That gives you room to use a slower shutter speed in bright conditions or a wider aperture without changing the light in the scene. It’s particularly handy for photographers who want to soften the movement of water, clouds or passing traffic, or who want to work with a wider aperture outdoors. The fixed reduction makes exposure planning straightforward: keep your ISO and aperture the same, then lengthen the shutter speed by three stops. For example, a shutter speed of 1\/125 sec becomes 1\/15 sec. This is a simple, specific tool rather than a variable filter; you get one set amount of light reduction. If that’s what your shot calls for, it can make bright-day exposure choices much easier.\u003c\/p\u003e\n\u003ch3\u003eUsing the three-stop reduction\u003c\/h3\u003e\n\u003cp\u003eFor a softer look in moving water, start with your normal exposure and slow the shutter by three stops with the filter in place. For portraits in bright light, you can instead open the aperture by three stops while keeping the same shutter speed and ISO. The right setting depends on the scene, but the filter’s reduction gives you a predictable shift to work with.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eThree stops means you can move from 1\/125 sec to 1\/15 sec without changing your aperture or ISO, which is useful when you want motion in a bright scene. I’d suggest this to someone photographing a stream or waterfall in daylight: keep the aperture and ISO steady, then use the slower shutter to soften the water. For a portrait outdoors, use the same reduction to open up the aperture instead. The 37 mm size is for a lens with a matching filter thread, so it’s worth matching that measurement to the lens you plan to use. One point to keep in mind: this is a fixed-strength filter, so it gives you three stops of reduction, not a range.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: B+W\u003c\/li\u003e\n\u003cli\u003eSeries: F-Pro\u003c\/li\u003e\n\u003cli\u003eType: ND filter\u003c\/li\u003e\n\u003cli\u003eDensity: 0.9\u003c\/li\u003e\n\u003cli\u003eCoating: MRC\u003c\/li\u003e\n\u003cli\u003eSize: 37\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"B+W","offers":[{"title":"Default Title","offer_id":57491969474900,"sku":"1070627BWF","price":47.17,"currency_code":"EUR","in_stock":true}],"url":"https:\/\/www.htf-store.com\/nl\/products\/b-w-f-pro-103-nd-0-9-mrc-37","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
