The 2 x 2" Tiffen 85B/ND Filter 2x2 3-Stopblends both an amber color conversion 85B and a 0.9 neutral density filter. The ND filtration provides a 3-stop exposure reduction for darkening the entire image in order to photograph with a wider aperture or slower shutter speed than normally required. The 85B filtration covers the entire filter plane and converts the color temperature to 3200K for use with type B (tungsten) films.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass, and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 2 x 2" / 50.8 x 50.8mm.

0.9 Optical Density    ColorCore Technology    Amber 85B and Neutral Density    Warming Filter to Decrease Color Temp    ND Filter to Increase Exposure Length

Combination of both an amber color conversion 85B and a neutral density filter.

0.9 ND filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.

85B filter converts the color temperature to 3200K, allowing you to use type B tungsten-balanced film in daylight situations.

Q: 10. Is there a way to stop the popping noise? It happens every time I mute and unmute myself.

A: After initial setup and the popping noises, I left for a couple of hours and came back, and... no more popping. I emailed Kopul customer support, and they shared the real answer: First, make sure the Mutemate is set to Dynamic mic setting. The Mutemate passes phantom power for condenser mics, so when switching to dynamic from condenser, you need to hold the button down for approx. 30 seconds to dissipate the phantom power stored in unit. Otherwise you will get the popping sound in the first initial uses. So make sure you are set to dynamic, and hold the button down for 30 seconds. This should alleviate any popping. I have a dynamic mic, but I had initially tried this on Condenser mode. That lingering power needed to dissipate before this could work as intended.
