This item is an older non F-Pro series Filter. Same Standard SC coated product. Exposed filter ring depth of this filter is 5mm versus the 4mm of the F-Pro Series


TheB&W Deep Blue KB12 Glass filterblocks so much red, orange and yellow that it increases the color temperature of very bright halogen and special photoflood lamps (of around 3400K) to that of daylight. With that kind of illumination, and with daylight color reversal film, the subjects will be reproduced in their original colors.

With weaker halogen bulbs or stronger incandescent bulbs in conjunction with this filter and with daylight reversal film, a residue of "warmth" will be retained for an optimal mood in interior photographs.
