The Tiffen 105mm 85 Color Conversion Filterhelps to decrease the color temperature from 5500 to 3400K, allowing the use of tungsten-balanced film in daylight conditions. The warming effect of this filter requires a 0.6-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: 10. Would this filter color balance the magenta and pink skin colors of indoor stage lights to normal skintones?

A: The Tiffen 77mm 80C Color Conversion Filter can do that, but only in very specific situations. The lights must be 3800K, you want to increase them to 5500K, and you are also using daylight film. If you are taking photos digitally it is much easier and more flexible to take photos in RAW and use the Datacolor SpyderCUBE RAW Calibration Tool BH #DAS3CQ. You take a photo of the cube under the lights, then use the white balance dropper in computer software such as Lightroom and click on the cube in the photo. The software will then remove the color cast and you can apply that same setting in the software to all of the other photos taken under the same lights.
