At least in my version of Photoshop (3.0.5), you can choose different
graphic modes (I don't have it in front of me, so I forget the exact menu)
such as RGB Color, CMYK Color, Indexed Color, etc.

One of the modes is "Grayscale", and if you select that while displaying a 
color image, Photoshop will throw away the colors, leaving you with a 
monochrome image.

You can also twiddle with the color saturation in Photoshop too, reducing
the saturation (color) level down to the minimum.
