The Tiffen 3 x 4" 3 Green Soft-Edge Graduated Filter helps to specifically add a bright green 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 less green coloration than the 4 density, but more 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 3 x 4" / 76.2 x 101.6mm.

Note: A horizontal orientation filter's line of transition runs parallel to the long side of the filter.

3 Density Color Graduated Filter    Green Coloring in Select Areas    Soft-Step Graduation    ColorCore Technology

Provides a bright green 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: 1. Is this a good fit for a 5'6 woman? I find that sometimes these bags are designed by men with men in mind...

A: I'm a 5'1 female and it works fine for me. The waist belt helps keep the weight of the backpack off the upper back, which is awesome because the shoulder straps aren't digging into my shoulders. I've hiked several trails through the Might 5 National Parks in Utah, Petrified Forest NP, Channel Islands NP with this backpack and did not feel that it is too big for my body.

A: I can barely fit in my ipad2 when loaded with gear. (MK IV - 70-200, 28-70, 50mm, batteries etc) The bag is not very flexible (which is good for protection) so outward expansion is minimal. I can rig the bag up to carry my MacBook when traveling but its very tight.
