The Tiffen 95mm Coarse Threads 1mm Streak Effect Filter is a cross screen filter providing one reflected light point stemming from specular highlights within the image frame. This effect is caused by thinly etched lines on one of the planes of the filter. These etched lines are spaced 1mm apart, producing visual depth and separation between light points in the resulting image. Streak effect filters are most effective when not used in conjunction with other filters.
Cross screen filter providing 1 reflected light point that stems from specular highlights within the image frame.
Streak effect is caused by thinly etched lines on the filter surface and does not affect exposure or coloration of the image.
Tiffen filters are 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, then mounting to precision metal rings.
