The Tiffen 77mm 82A Light Balancing Filterhelps to increase the color temperature by 200K in order to cool the image slightly in order to match the color quality of illumination. When using an 82A filter, you will be able to attain 3200K balance when the prevailing light source is 3000K. The cooling 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.

Light balancing filter increases color temperature and provides a cooling effect.

Adds 200K in order to attain 3200K color balance from 3000K illumination.

Filter factor of 1.3 requires a 0.3-stop increase in exposure.

Q: 1. I want to achieve vivid, saturated colors in scenes with lots of natural light. Will this filter help me with that?

A: The use of hte Tiffen 82mm Variable Neutral Density Filter is to reduce the amount of light getting to through the lens. Many use this to shoot wide open and or at a very slow shutter speed. It is not made to increase saturation.

Q: 2. It is really worth to have this filter when using a lot of nd filtering? Like to use nd1.2 and nd9 combined when shooting for ex 4K with a A7S? Do you really noticemthat difference?

Q: 5. Can I mount this on top of a circular polarizing filter? Is there a downside to doing that?

A: The Tiffen VND filter consists of two circular polarizing filters...two CP filters together create the VND effect. Mounting this on top of a circular polarizing filter may cause some undersired effects such as cross polarization, vignetting in addition to difficulty adjusting the two filters as both turn and are adjusted by hand... if you mount the CP, then the VND it would be difficult to control both as they are turning. We recommend using a straight ND and then a CP instead.

Q: 6. How does this filter effect skin tones would an orange 23a be better?

A: This filter is designed to effect contrast in B&W photography, it is not recommended for color photography as the entire image would be red.

Q: 7. Hello, I did read a review telling that when using a IR/UV Cut filter on Wide Angle Lenses the image can be compromised: the interference varies with the angle of incidence of the light on the glass. This renders this filter unusable with wide-angle and even normal focal lenses, resulting in a greenish gradient from the center to the corners. - this was posted for the 72mm version of an IR/UV Cut filter of another brand.- Q: Did someone else has this problem on Full Frame & APS-C DSLRs with Wide Angle Lenses like 16mm with THIS Tiffen W77IR filter?Thank you very much!

A: Hi HD Cam T,I purchased this filter to correct a known IR contamination defect in the Sony EX-1 camcorder. Black suits turn different shades of brown depending on their material without the filter. An orchestra of black suits will look like everyone is wearing a different shade of off black tuxes. But some will be true black. I only use the filter when I need it. I manually white balance the camera when using the IR filter. The image has a green cast if you do not white balance. You also loose about a half an f stop with the filter. Not a perfect fix for my camera but it is the only one I have found.

Q: 8. What is the filter factor for Tiffen 812 warming filter? Can I use canon software to warm up skin tone instead of buying this filter? If yes, how much correction in software will I need to mimic the effect of this filter?
