The Tiffen 82mm 81B Light Balancing Filter helps to decrease the color temperature by 300K in order to warm the image slightly in order to match the color quality of illumination. When using an 81B filter, you will be able to attain 3200K balance when the prevailing light source is 3500K. The warming effect of this filter requires a 0.3-stop increase in exposure for normal results.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.

Q: 3. If I use this filter to block light from distant city, will it also affect the Halogen light I use to light paint?

A: The Kase Neutral Night Light Pollution Filter (82mm) is designed to reduce light pollution when photographing the sky during long-exposure night photography. It was not originally intended for light painting usage needs. Halogen lights will output light that may be suppressed by the filter, but it may depend on the intensity of the light as to the effect the filter may have on the halogen light (the filter is designed to reduce background light glow). Your results may vary, and would require testing to see if it would work for your planned usage needs.
