The 1-stop, 86mm Coarse Tiffen 81EF/ND Light Balancing Filter 86mmcombines the effects of an 81EF light balancing filter with a neutral density filter. 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 filters appear gray and reduce the amount of light entering the lens. They have no effect on color balance and are very useful when you want to shoot high-speed film outdoors on a very bright day.

Tiffen's ColorCore glass is produced through a process that entails permanently laminating the filter material in between two pieces of optical glass that are ground flat to tolerances of 1/10,000th of an inch, then mounted in precision aluminum rings. This process makes for greater accuracy of color as opposed to glass that is simply dyed and become subject to deviation during the dye process.

• Good for general scenics when the photographer wishes to remove the bluish cast from open shade or just add warmth to the photograph, with an 81EF having the greatest effect
  
  81 Series Conversion Factors
• 81 decreases color temperature from 3300 to 3200K
• 81A decreases color temperature from 3400 to 3200K
• 81B decreases color temperature from 3500 to 3200K
• 81C decreases color temperature from 3600 to 3200K
• 81D decreases color temperature from 3700 to 3200K
• 81EF decreases color temperature from 3900 to 3200K

• Enable slow shutter speeds to be used, especially with high speed films, to record movement in subjects such as waterfalls, clouds, or cars
• Decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their backgrounds
• Allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand, or other bright scenes that could cause overexposure
  
  Neutral Density Factors
• ND 0.3 (exposure adjustment = 1 stop, reduces ISO 1/2)
• ND 0.6 (exposure adjustment = 2 stops, reduces ISO 1/4)
• ND 0.9 (exposure adjustment = 3 stops, reduces ISO 1/8)

Q: 4. will these filters fit on my Nikon D3200 dslr camera?

A: 55mm is a filter size used by The 55mm filter size is currently only directly compatible with a 1 NIKKOR 10-100mm f/4.0-5.6 VR. The question may be: will the 55mm filters fit on the lens that is mounted to the D3200. Since the filters screw into the front of the lens then the lens would be the determining factor. The typical kit lenses for the D3200 accept 52mm screw in filters. If your lens accepts 52mm size filters you may want to consider buying the 52mm size versus the 55mm size. The other alternative is to buy a step-down ring from 55mm to 52mm - B&H sells the step-down rings, just use their site search and enter Step Down Ring . Then you should be fine. Hope this helps.

Q: 6. The spec says Front Filter Thread Size86mm , so can I use a normal 86mm lens cap on the outside of the filter? Thanks!

A: You should be able to use you 77mm lens cap. I do with mine.

Q: 7. Any discoloration with the filter?

A: It depends on your camera. If you can white balance with the filter applied to the lens then you should be fine. I've had no issues and in general I don't worry about IR pollution.

Q: 8. Can the Tiffen 77 MM Variable Neutral Density filter be stacked on top of these filters and if so, does doing so cause any color issues?

A: Yes, you can stack the 77VND filter on top of these. Depending upon which camera body/sensor you have, how long your exposure is and how much IR light there is present in your scene you may experience IR pollution resulting in a color shift. You may want to consider the Tiffen Apex filter instead, which is a 10 stop filter designed for long exposures with IR protection up to 1100nm.a href= https://www.bhphotovideo.com/c/product/1107539-REG/tiffen_77irnd30hm_77mm_apex_irnd3_0hm_filter.html target= _blank https://www.bhphotovideo.com/c/product/1107539-REG/tiffen_77irnd30hm_77mm_apex_irnd3_0hm_filter.html/a

Q: 10. Why in the world would you use this awful simulated image?

A: If you don't understand what the picture is showing, then you are not qualified to use this product. ND filters are used to reduce the amount of light entering the camera so that you can drag or slow down the shutter creating a soft water affect. This filter is also used in other special effect situations for video. I have worked on film productions for some of the largest production companies in the world and this is my go to filter.
