The Tiffen 5.65 x 5.65" Smoque 3 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 3 density provides more smoke effect than the 2, but less than the 4.
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 5.65 x 5.65" / 143.5 x 143.5mm.
