Well made

Did a test shot. WB set to sun. Focus set to manual. Aperture set to f/16. ISO set to 200. Mounted on tripod with shutter release cable. No filter - the shutter speed was 1/30 sec. With filter, shutter speed 2.5 seconds. Approx 6x exposure time, which matches advertised ratio of 1:128. HOWEVER, the shot with the filter had a decided greenish-aqua color cast. This color cast can be removed easily in post processing.

Tiffen W77IRND21 77mm Filter

Using it as a standalone and also in combination with another ND filter to further increase the stops; minimal tint

good filter for long exposure

These are the #1 piece of gear to grab for shooting on DSLR's during bright, sunny lighting conditions.  The whole series of IRND filters by Tiffin allow you to shoot at shallow depth of field to create that iconic, filmic look.
