This 86mm Tiffen ND Filter is a solid ND filter with a filter factor of 2.5x that provides a 1.3-stop exposure reduction. Its 0.4 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.

A: The Tiffen Solar ND Filter (95mm, 18-Stop, Special 50th Anniversary Edition) (B&H# TI95CND54) is absolutely suitable for photographing any annular solar eclipse such as the one on October 14, 2023 (and future such annular solar eclipses), as well as any total solar eclipse such as the one on April 8, 2024 -- and later ones, too, in 2026, 2028, etc. As with any similar photography (rather than optical viewing) style filter, the image would then be viewed using electronic means such as in digital live view mode when using a DSLR (rather than using the optical viewfinder) or with any mirrorless camera using its digital viewfinder or rear digital screen.
