The Tiffen 4 Green Soft-Edge Graduated Filter 5x6"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 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 5 x 6" / 127 x 152.4mm.

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    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: 3. Would this ND filter be suitable for solar event photography?

A: The K&F Concept Nano-X Pro Green ND1000 Filter (105mm) should not be used for solar photography. ND alone does not block the harmful rays that can damage eyes and camera sensors. For solar photography, use a solar filter that is 12312-2 ISO certified. Filters with this certification will stop more than 99.999% of intense light, plus 100% of harmful IR and UV radiation.

Q: 7. I see there's lots of ND options for this. What will be a good recommendation for a first horizon ND filter, let's say for the sea shore and landscapes (Horseshoe Bend in Page AZ)? Thanks.

A: Most of the photos of Horseshoe Bend feature an area of landscape where there is a straight horizon without trees, mountains, or buildings between the bright sky above and the rock formation below. As such, a very hard edge filter attenuating the sky's light by three stops (0.9 ND) such as the LEE Filters 100 x 150mm Very Hard Graduated Neutral Density 0.9 Filter (B&H# LEGND.9VH46) would be ideal for that: https://bhpho.to/3tSwgZs
