The Tiffen 4 x 4" 3 Grape Solid Color Filter adds a vivid, purple coloration across the entire image and helps to cool overly warm tones. The solid color design makes this filter well-suited to pairing with other filters for further control over the appearance of imagery. The 3 color density provides more grape coloration than the 2 density filter.
This filter is 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. It measures 4 x 4" / 101.6 x 101.6mm.
