The Formatt 5x5" Combination Light Balancing 81EF/Neutral Density (ND) 1.2 Schott-Desag B270 Crown Optical Glass Filter combines the effects of an 81EF Light Balancing filter with a Neutral Density filter.
81EF
An 81EF filter (the strongest in the 81 series) will more than replace the yellow missing from the image and place all skin tones on a distinctly "warmish" level.
Neutral Density (ND)
ND filters appear grey and reduce the amount of light reaching the film; they have no effect on color balance. They are very useful when you want to shoot high-speed film outdoors on a very bright day.
Formatt, a company with three generations of professional filter-making experience, produces every filter to the highest technical standards. The finest materials, together with state of-the-art production technology, have resulted in a standard of optical excellence unmatched anywhere else.
Neutral Density filters have four main uses
- To enable slow shutter speeds to be used, especially with high-speed film, 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 situations
- 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)
- ND 1.2 (exposure adjustment = 4-stops, reduces ISO 1/16
