The Tiffen 4 x 5" 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" / 101.6 x 127mm.

Note: A vertical orientation filter's line of transition runs parallel to the short 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.

Related Questions and Answers

Q: 1. Is the mechanic of accessing the camera (use waist belt, rotate the bag to front) exactly the same as Lowepro Photo Hatchback?

A: Yes, this back will allow you access the gear in the way you describe, similar to the Lowepro Photo Hatchback. This is also illustrated in the product images.

Q: 2. Will this pack hold Canon 5D Mk III with 70-200mm lens attached, including lens hood?

A: To hold the Canon EOS 5D Mark III with the Canon 70-200mm f/2.8L EF II IS USM lens along with the lens hood all connected, the Lowepro Flipside Trek BP 450 AW Backpack (Gray/Dark Green) B&H # LOFTBP450AWB, would instead be recommended for your needs. The Lowepro Flipside Trek BP 350 AW Backpack may work if the items are not connected and the interior is customized for the gear, but is not recommended if the above items are to be used together while connected to each other.

Q: 3. Will a Peak Capture plate attach to the straps on this pack?

A: As the bag itself has no arca-swiss clamp, there will be no way to attach the plate to the bag. However, if you mean attaching the Peak Design Capture Clip system, there are several places where the clip can be attached. The straps taper out and can be snuggly fit over the thickest part of the material. If your equipment isn't too heavy (medium-SLR or mirrorless) you can also attach it to several of the thinner-material straps that are on the main shoulder straps. In either case, we recommend that you use the hex-head fastening screws rather than the normal ones.
