The cokin p series p005 sepia filter tints photographs with an antique brownish hue giving the appearance of an overall nostalgic turn of the century look this gives the illusion of an image taken years ago in black and white that has in fact only been shot in this present time the cokin 045 is also a sepia filter however the effect is not as strong this filter measures 85 x 85mm and fits the cokin p series holder
