The Tiffen 138mm Tropic Blue Color Filteradds a cool, aqueous coloration across the entire image and helps to subdue overly reddish casts. The solid color design makes this filter well-suited to pairing with other filters for further control over the appearance of imagery. The 3 color density provides more tropic blue coloration than the 2 density filter.

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.

3 Density Solid Color Filter    Cool Tropic Blue Coloration    ColorCore Technology

Tropic blue-colored filter provides a cooling effect to your images and reduces red and yellowish casts.

Solid color filters apply the amount of density evenly across the image plane in order to achieve a fluid and creative effect.

Q: 1. Hi,I own the Bright Tangerine Misfit Atom. I only see the Misfit in the compatibility list. Do you know if it will work? Thanks

A: Sorry, but the Tiffen 138mm Variable ND in Matte Box Mountable Rubber Donut for 143mm Openings is too big. The front, the part that mates with the matte box holds is 143mm so it can hold the 138mm filter. This means it is bigger than the rear of the Misfit Atom which takes a maximum of 114mm. To do what you wish, you may have to go with a screw in 114mm filter or another matte box.
