About Tiffen W77IRND21

Tiffen IR ND filters do not have a sharp cutoff at the infrared wavelengths; therefore the wide color gamut these sensors record is not compromised. The result is vibrant colors and no IR contamination, with crisp clean images that only Water White glass can deliver. These filters also provide a greater latitude when editing in post production and are ideal for 8 byte compressed color.

Tiffen W77IRND21 Features

  • High quality filter to prevent the color shift caused by the sensitivity of today's digital sensors
  • Tiffen filters are manufactured using ColorCore technology, a closely guarded proprietary process that entails permanently laminating the filter material in between two pieces of optical glass that are ground flat to tolerances of a 10,000th of an inch, then mounting them in precision metal rings
  • The ColorCore process allows Tiffen to control the color and density of their filters and the characteristics of special effects filters with much greater accuracy than typical dyed-in-the-mass filters, which usually exhibit color and density variations
  • Natural Density Filters enables slow shutter speeds to be used, especially with high speed films, to record movement in subjects such as waterfalls, clouds, or cars
  • Natural Density Filters decreases depth of field by allowing wider apertures to be used, which helps separate subjects from their background
  • Natural Density Filters decreases the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situation
  • Natural Density Filters allows cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure
  • Minimizes IR Contamination of Images

Tiffen W77IRND21 77mm Filter

By

from Bel Air, Maryland  -  Photo Enthusiast

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.

good filter for long exposure

By

from Vancouver, BC  -  Semi-pro Photographer

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

Absolutely essential for DSLR Filming

By

from SLC, Utah  -  Pro Photographer

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.

Questions about this item:

karla o  can this filter be used for solar eclipse photos?
Jason H  Baader solar film is specifically designed for viewing the sun-I wouldn't use anything else as some other methods might seem safe but still allow damaging uv radiation to pass through to your eyes. Baader solar film is cheap and effective and protects your eyes completely.
