Tiffen 4 x 4" Neutral Density (ND) 1.8 Filters have several uses and offer the possibility to achieve otherwise unachievable results. They enable the shooter to adjust exposure without affecting color balance. ND filters appear gray and reduce the amount of light reaching the film.
Determining which neutral density filter yields ideal results for any given lighting situation takes knowledge, experience and a collection of such filters. Speaking generally, the 2-stop value (ND 0.6) effectively compensates average situations.
Neutral Density Filters Have Four Main Uses:
- To enable slow shutter speeds to be used, especially with high speed films, to record movement in subjects such as waterfalls, clouds, or cars
- To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background
- To decrease the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situation
- To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure
Neutral Density Factors
- ND.3 (exposure adjustment = 1 stop, reduces ISO 1/2)
- ND.6 (exposure adjustment = 2 stops, reduces ISO 1/4)
- ND.9 (exposure adjustment = 3 stops, reduces ISO 1/8)
- ND1.2 (exposure adjustment = 4 stops, reduces ISO 1/16)
- ND1.5 (exposure adjustment = 5 stops, reduces ISO 1/32)
- ND 1.8 (exposure adjustment = approx. 6 stops, transmits 1% of light)
- ND 3.0 (exposure adjustment = 10 stops, transmits 0.1% of light)
- ND 4.0 (exposure adjustment = 13-2/3 stops, transmits 0.01% of light)
- ND 6.0 = (exposure adjustment = approx. 20 stops)
- Tiffen filters are manufactured using ColorCore technology, a closely guarded proprietary process that entails permanently laminating the filter material in between two pieces of optical glass that are ground flat to tolerances of a ten-thousandth of an inch, then mounting them in precision metal rings
- The ColorCore process allows Tiffen to control the color and density of their filters, and the characteristics of special effects filters with much greater accuracy than typical dyed-in-the-mass filters, which usually exhibit color and density variations
- Top Hollywood motion picture studios rely on Tiffen filters for their multimillion-dollar productions Superior quality and design make Tiffen the overwhelming choice of moviemakers, professional photographers and even NASA
- Tiffen has also been awarded an Emmy, from the Academy of Television Arts and Sciences, for its engineering excellence
Australian Shipping Via DHL
DHL offers a great express shipping service to Australia from New Zealand. We are proud to be able to offer express shipping to main cities on the east coast of Australia, within the same timeframe ( If not quicker ) than local Australian courier companies. Prior to the Covid-19 outbreak, service standards for these main centers was overnight. However these services have been impacted greatly, and as such the overnight service has been suspended.
