The Tiffen 86mm 82C Light Balancing Filter helps to increase the color temperature by 400K in order to cool the image slightly in order to match the color quality of illumination. When using an 82C filter, you will be able to attain 3200K balance when the prevailing light source is 2800K. The cooling 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: 1. What is the small number I get after my reading in F mode: EG 125s (small 6)?

A: The 478 display can be set to readout in full stops with 1/10 (which is the number you are referring to), Third Stops (which is what most cameras use), and Half stops (which is what older, manual camera lenses use).
