67mm Red Dark 630 (091) MRC Basic

 Compared with the lighter B+W 090 red filter 590 also in the range, the B+W 091 red filter 630 delivers a further intensification because it even darkens the yellow close to red in the spectrum, and its transparency does not come into play until the orange-red zone. It produces dramatic effects and extreme posterization for a graphic effect.
