The Tiffen 4x5.65" Red Soft-Edge Graduated Filterhelps to specifically add a warm, bright red 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 3 color density provides less red coloration than the 4 density, but more 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 5.65" / 101.6 x 143.5mm.

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

3 Density Color Graduated Filter    Red Coloring in Select Areas    Soft-Step Graduation    ColorCore Technology

Provides a bright red 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: 2. What options do I have for a filter holder for this 150 X 170mm ND 0.9 filter

A: The 150 X 170mm filters are designed for the Lee SW150 filter holder (B&H # LEFHN1424). If you have a lens other than the Nikon 14-24mm f/2.8, you would also need the SW-150 system adapter (B&H# LESW150A) to use the filter holder with the existing Lee adapter rings for standard filter thread sizes.

I live in Key West and we have very bright sunny conditions. Thanks for your help

A: To use these filters effectively with your Canon 10-22mm lens that has a 77mm front diameter, you would need the Cokin BPW400 Wide Angle Filter Holder for P Series, B&H# COWAFHP along with the Cokin P Series Filter Holder Adapter Ring (77mm), B&H # COARP77. https://bhpho.to/2lV7TeJ https://bhpho.to/2WfVmzm

Q: 6. I noticed reviews on Nisi soft grad ND filters, that the transition is very long. the dark section dosn't start until very high up on the filter. The Nisi Hard edge has a smaller transition, it almost looks more comparable to a soft edge.their soft looks more comparable to a blender. dose anyone have any hands on experience with the soft edge ND vs the hard edge ND. If so is my observation true?Thanks

A: I have found the hard grad lies somewhere around the medium grads that some other companies have. Their soft has a much more gradual transition than most other companies though. I have found it to me much more forgiving than most other soft grads.
