The Tiffen 4"x4" Tropic Blue Soft-Edge Filterhelps 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 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 and grinding flat to a tolerance of 1/10,000th of an inch. It measures 4 x 4" / 101.6 x 101.6mm.

3 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: 6. is this filter a good size for a 77mm lens or I would be better off with a 100mm size filter ?

A: It depends if youre shooting wide or not. Im thinking you probably are so I wouldnt recommend it. Anything roughly under about 25mm brings the holder into the frame. So basically it was a waste of money for my 17-35 nikkor lens with 77mm thread. Id go for a bigger filter kit if shooting anything wide, 24mm or wider. Hope that helps.
