The Tiffen 3x4" Cool Blue Soft-Edge Graduated Filterhelps to specifically add a cool, purplish-blue 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 cool blue 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 3 x 4" / 76.2 x 101.6mm.

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

4 Density Color Graduated Filter    Cool Blue Coloring in Select Areas    Soft-Step Graduation    ColorCore Technology

Provides a deep cool blue 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: 7. I have the 100 -400 canon lens. what exactly do I need to use this setup? Please be specific. Thank you

A: Hi Patricia,As far as I could research, there are two Canon lenses that fit your description. One has image stabilization (IS) while the other does not. The Canon EF 100mm f/2.8 Macro USM has a filter diameter of 58mm and would require this: https://a href= http://www.bhphotovideo.com/c/product/14092-REG/Cokin_CP458_P_Series_58mm_Adapter.html target= _blank www.bhphotovideo.com/c/product/14092-REG/Cokin_CP458_P_Series_58mm_Adapter.html/aThe Canon EF 100mm f/2.8L Macro IS USM has a filter diameter of 67mm and would require this: https://a href= http://www.bhphotovideo.com/c/product/14094-REG/Cokin_CP467_P_Series_67mm_Adapter.html target= _blank www.bhphotovideo.com/c/product/14094-REG/Cokin_CP467_P_Series_67mm_Adapter.html/aIf neither of these match the lens you own, then the item you are looking for is a Cokin P Series Filter Holder Adapter Ring in the appropriate size. The kit already includes the filter holder, which simply slides onto the adapter ring. These are nice filters, I've enjoyed them very much so far. Best of luck!

Q: 8. Does the filter holder rotate like the Lee system?

A: Yes, the Cokin Z-Pro holder rotates.

Q: 9. Does this fit the Lee SW150 filter holder?

A: Yes, it will. But, you need to keep in mind this product is designed to split the ND/non-ND parts vertically. Under normal use, the ND portion would be placed over sky while the clear portion covers the landscape. Using this filter with the SW150 holder would result in the ND/non-ND portions split left-right horizontally instead of vertically.

Q: 10. I just bought the Cannon 10-22mm lens with 77mm... is this a good graduated neutral density kit to use with a wide angle lens? do I need to purchase anything else for this particular kit to work on my Canon 60D? 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
