Bay IV - B11 blue color filter for Rolleiwide, Rolleiflex FW and other bayonet IV mount TLR's
Rollei B11, Blue, Filter is a color conversion glass filter. The filter is a light balancing filter used to maximize the color temperature for a cooler tone. It absorbs the excessive yellow-red light from artificial, tungsten or incandescent lighting and renders red darker. The filter also maintains natural flesh tones while preventing reddish cast. It can be used for other creative ways with black and white film. It has a Bay IV filter size which is not too common.
This filter is in very good condition with no scratches or delamination.
