The Tiffen 5 x 6" Smoque 4 Filter is a unique diffusion filter that provides a smoky, hazy quality to your images, emulating the effects of a smoke or fog machine. This filter is ideal for use in situations where smoke could typically be encountered, but is not available or present. The 4 density provides more smoke effect than the 3.

Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 5 x 6" / 127 x 152.4mm.
