It suits filmmakers and other image-makers working with a 4x4 filter setup who need to reduce incoming light without changing their chosen aperture or shutter setting. A density of 2.4 is approximately eight stops of light reduction, a substantial cut that can help preserve a wide aperture outdoors or support long exposures in daylight. The IRND designation indicates that the filter is intended to manage infrared as well as visible light. That makes it a considered option when infrared behaviour matters to your image, rather than simply reaching for a strong ND filter. Its fixed density is useful when you know the reduction you need; it’s less flexible if light levels are changing quickly.\u003c\/p\u003e\n\u003ch3\u003eChoosing the right exposure\u003c\/h3\u003e\n\u003cp\u003eThink of this as a filter for a planned exposure, not a small, on-the-fly adjustment. An approximately eight-stop reduction gives you room to use a slower shutter or wider aperture in bright surroundings, but you’ll want to settle your exposure around that fixed amount. For a long-exposure still, for instance, the reduction can help turn a fast daylight shutter into a multi-second exposure. In a moving-image workflow, it can help retain your intended shutter setting while managing excess light.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eThe Tokina 4x4 Pro IRND 2.4 is best at making a major exposure cut while addressing infrared. I’d point it out to a filmmaker already working with a 4x4 filter holder, especially for bright-day scenes where you want to keep your chosen shutter and aperture. Its 2.4 density is roughly eight stops: for a static daylight scene, that can take a 1\/125-second exposure to around two seconds, assuming the light stays the same. The 4x4 format also gives you a clear format requirement to match to your filter setup. My honest caution: that’s a strong, fixed reduction, so it’s not the one I’d reach for when you need small, frequent exposure changes.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFormat: 4x4\u003c\/li\u003e\n\u003cli\u003eFilter type: IRND\u003c\/li\u003e\n\u003cli\u003eDensity: 2.4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tokina","offers":[{"title":"Default Title","offer_id":57503593333076,"sku":"TO-CIRND24P4X4","price":165.77,"currency_code":"EUR","in_stock":true}],"url":"https:\/\/www.htf-store.com\/zh\/products\/tokina-4x4-pro-irnd-2-4","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
