The Lee RF75 Deluxe Set gives you the tools to get some great outdoor images.
Neutral Density Filters
The Lee RF75 Standard Neutral Density (ND) 0.3 Filter has several uses and offers the possibility to achieve otherwise unachievable results. ND filters appear grey and reduce the amount of light reaching the film. They have no effect on color balance.
The Lee RF75 Rangefinder Filter Holder System offers a small, portable, flexible filter system to users of all camera formats. From small, high-end digital cameras to traditional medium and large format shooters, the RF75 is designed with a lightweight and compact design making it a perfect choice for outdoor shooting.
This system was originally targeted for small, rangefinder point-and-shoot users. However, it is an eminently viable alternative for anyone needing a compact, full-featured filter system at a reasonable price point. Film shooters as well will find this system of great benefit.
The system holds filters sized 75 x 90mm. The front assembly of the holder has been laser etched for repeatable positioning of the holder. In that way, graduated filters can be used over and over again with the same results. This is a huge benefit to rangefinder users who cannot see the effects of the filters through their viewfinder. The two filters slots on the holder have been designed to cover the widest lenses available in today's market.
This filter, part of the RF75 system, attaches to the four studs on the front of the holder. Twist and click action secures the filter.
Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast. The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun.
Note: Adapter Rings sold separately
- Polarizing Filter
- This filter eliminates ultraviolet rays to remove haze from outdoor shots as well as polarizing the light to remove reflections, and increase color saturation, without affecting the overall color balance
Neutral Density Filters
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 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)
