The Tiffen 6 x 6" 2 Tropic Blue Soft-Edge Graduated Filter helps to specifically add a cool, greenish-blue coloration to skies and other bright areas of an image while allowing a portion of the image to remain neutrally colored. The filter's coloring is densest at the edge and tapers to clear by the middle, with a soft-edged transition between the density and clear areas. The 2 color density provides less tropic blue coloration than the 3 density, but more than the 1 density filter.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. It measures 6 x 6" / 152.4 x 152.4mm.

2 Density Color Graduated Filter    Tropic Blue Coloring in Select Areas    Soft-Step Graduation    ColorCore Technology

Provides a deep greenish blue coloring to select areas of the image.

Graduated filter design keeps a portion of the image neutral, resulting in a more realistic look while allowing for the sky or other bright areas to take on the color of the density.

Q: 10. is this the right size for 77mm and what filter holder should i use ?

A: Yes, this will fit both 77mm and 82mm lenses. I have the Lee 4x6 standard foundation kit. Youll have to get an adaptor ring for your lens (77mm) that the foundation kit holder snaps onto. Its a simple set up, rock solid and easy to take on/off the lens. The same foundation kit will work for several other lenses, you just need the appropriate lens ring adaptor.. Ive been very happy with the set up and filters.
