The Tiffen 4x5" Cyan Soft-Edge Graduated Filterhelps to specifically add a bright cyan 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 1 color density provides less cyan 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 5" / 101.6 x 127mm.

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

1 Density Color Graduated Filter    Cyan Coloring in Select Areas    Soft-Step Graduation    ColorCore Technology

Provides a bright cyan 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: 8. what is the cartridge capacity on these?

A: The cyan 200 is a standard capacity cartridge. Epson provides some specifications on cartridge performance at their website, cartridgeinfo. How long they last and how many prints you can get depends on what type of printing you are doing. If you are printing 8.5 x 11 full color photo quality photo prints, where the entire paper surface is printed, the cartridge might need replacement after only 10 or 15 photos. If you print only Word docs or web pages on a draft setting, the cartridge will last for probably 80 pages at least. If you print very seldom, you will not get as many prints because the heads will need cleaning and that uses ink. Hope this helps.
