The ND32000 15 Stop NiSi Filter is constructed from the highest quality optical glass. For all sizes we exclusively offer the highest quality optical glass and NiSi Nano® Coating technology.
The ND32000 (4.5) absorbs 15 stops of light, thus enabling longer exposure times even in strong light. To calculate exposure times, the shutter speed without the ND filter needs to be multiplied by 32000. For example, if we get a “correct” exposure by shooting without the filter with a shutter speed of 1/250? (i.e. 0.004?), multiplying this value by 32000 we get 128? as the shutter speed to be used by mounting the ND32000 15 Stop filter. That is approximately 2 Minutes.
Multi-coating, the use of Nano® technology and optical glass guarantee the highest quality and make this 15-stop ND filter the most advanced on the market. All NiSi ND and GND filters include IR treatment, which blocks infrared light and makes NiSi filters the best in the market for colour matching.
