Compared with the lighter B+W 090 red filter 590 described earlier, 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.<b>Tip</b>The contrast can be increased in a digital camera by taking the picture directly in the black and white mode.
