The  Tiffen Sepia Solid Color Filteradds a warm, pale greenish-brown coloration across the entire image to provide a nostalgic, old-fashioned appearance. 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 sepia 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, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings. Sepia-colored filter provides a warm, greenish-brown coloring and gives an old-fashioned appearance to your images. Solid color filters apply the amount of density evenly across the image plane in order to achieve a fluid and creative effect.
Gives an old-time feeling to new images.
