It’s for photographers who need to reduce the light reaching the camera while keeping the scene’s colours and contrast unaffected. The filter works across the visible spectrum, so its effect is an even reduction in light rather than a shift in colour. That makes it useful for lengthening shutter times in bright conditions: render moving water with a smoother appearance, show movement in passing clouds, or use a slower shutter speed to convey motion in a busy street. In each case, the filter’s role is the same: reduce incoming light so you can use a longer exposure under the same lighting. The defining detail here is its neutral-gray glass and even spectral response, rather than a stated exposure factor. It’s a straightforward option for photographers who want shutter-time control without changing the scene’s colour balance or contrast.\u003c\/p\u003e\n\u003ch3 data-section=\"features\"\u003eIn the field\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeutral-gray Schott NG glass:\u003c\/strong\u003e The glass reduces light while leaving colours and contrast unaffected.

Its neutral-gray Schott NG glass reduces light evenly, so the longer shutter time comes without a colour or contrast shift. I’d point to the 55 mm version for someone whose lens takes that size, especially for water or passing clouds in bright conditions. The exact shutter speed depends on the scene and exposure you choose, so I wouldn’t promise a particular result from the filter name alone. Its job is clear: reduce light for longer exposures.\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\u003eModel: 102 ND Gray 55 E\u003c\/li\u003e\n\u003cli\u003eType: Neutral-density (ND) filter\u003c\/li\u003e\n\u003cli\u003eFilter size: 55 mm\u003c\/li\u003e\n\u003cli\u003eGlass: Schott NG neutral-gray glass\u003c\/li\u003e\n\u003cli\u003eLight control: Reduces incoming light\u003c\/li\u003e\n\u003cli\u003eSpectral effect: Blocks visible light evenly\u003c\/li\u003e\n\u003cli\u003eColour effect: Colours remain unaffected\u003c\/li\u003e\n\u003cli\u003eContrast effect: Contrast remains unaffected\u003c\/li\u003e\n\u003cli\u003eUse: Supports longer shutter times under the same lighting\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"B+W","offers":[{"title":"Default Title","offer_id":57453482934612,"sku":"72865BWF","price":26.99,"currency_code":"EUR","in_stock":true}],"url":"https:\/\/www.htf-store.com\/zh\/products\/b-w-102-nd-gray-55-e","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
