The Tiffen 4 x 5.65" 4 Green Hard-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 hard-edged transition between the density and clear areas. The 4 color density provides less green coloration than the 5 density, but more than the 3 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 5.65" / 101.6 x 143.5mm.

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

4 Density Color Graduated Filter    Green Coloring in Select Areas    Hard-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. I'm looking for a bag that I can carry a camera with 2-3 lenses, and about 3 days worth of clothes. Is there enough room in this bag?

A: You won't fit 3 days of clothes in here. Unless you're in the tropics and only need a fresh T-shirt. There's room for a compact jacket, or a good compressible down jacket.

Q: 2. I have Whistler 450 AW II. Does this one offer more space for other hiking noncamera gear or it is just smaller overall?

A: The Lowepro Flipside Trek BP 450 AW Backpack (Gray/Dark Green) is larger than the Whistler 450 AW II. So, the camera compartment and the Top compartment are larger.

Q: 4. Can you store a 13 or 15 laptop in this backpack?

Q: 5. Anyone know why the 450 is less expensive than the 350?

Q: 6. Do you think this can be used for a large format system?
