The Tiffen 4x4" Dark Blue 47B Glass filter is a dark blue filter that lightens blue objects for detail. Want clearer water? Lighter skies? Enter the 47B filter. It should be noted that the almost 3-stop loss of light this filter commands would almost certainly dictate the use of a tripod.
Filters for black and white photography perform a variety of filtration effects including contrast control, enhanced skin tones, tonal corrections and more dramatic landscapes
Although originally intended for use with black and white film, this filter can also be used as a creative tool in color imaging
