The Tiffen 4x4" Straw Soft-Edge Graduated Filterhelps to specifically add a warm, golden yellow 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 straw 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.

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

Provides a golden yellow 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: 4. I am looking into buying this filter for shooting sunrises and sets where the mountains and forests are very shade compared to the sky. Should I go for something darker or lighter?

A: There is no definitive answer to your question based upon the information provided. Your question depends on the difference in correct exposure value between the mountains/forest and the sky. Each .3 of ND is equal to one stop of light loss. If the difference in exposure values is two stops, go with a graduated ND .6, if it is three stops then use a .9, etc. For best results, keep a few of these filters in your camera bag with varying ND densities.
