Convert to Black & White

[Andrew B.]

For B/W conversion, here is a method I picked up from one of the Russell Brown tutorials:

Add two hue/saturation layer masks. On the top one, turn saturation all way down. On the lower of the two, set it to Color blending mode. And it is in this lower one where you will do all your adjusting. For example, the hue slider takes you through the range of color-to-bw filters. The saturation slider affects the intensity. Using the drop down in the hue/saturation adjustment layer lets you target one color in the conversion. And using the range sliders at the bottom of the hue/saturation adjustment layer lets you adjust the range of color that is targeted.

In many ways, this method is much easier and more powerful.
