If you’ve ever used graduated ND filters on your DSLR, you are likely aware of how the ND begins in the center of the filter, and this can impact how you compose your shot. I’m talking about the “x” pattern that can appear of your ND isn’t lined up properly. Still photos aside though, when recording a moving image (video) and adjusting your horizon, specifically where the graduation of that ND begins might be problematic. Tiffen has decided to release a series of screw on filters in a range of sizes that gradate from clear to ND over the entire span of the filter, rather than starting in the center, hoping to make it easier for filmmakers to utilize the benefits of a grad-ND.
Tiffen has made filters like this before (for matteboxes) and they are know as “Blender” filters. This is the first time they will be available as screw-on filters, with an adjustable ring to set the horizon, similar to how a circular polarizer works. Sizes will include 40.5, 43, 46, 49, 52, 55, 58, 62, 72, 77 and 82mm. They are currently available on Tiffen’s website.
