As Diane said, it's a simple conversion in the camera, but better done
manually after the fact. Different images have important detail in different
color channels, so for best results you should always look at the three
color channels separately, and try various mixes of them, for the best
effect. For instance, to dramatically darken a blue sky, you use primarily
the red channel, and sometimes even subtract some of the blue channel. But
there is no single conversion formula that produces the best result for all
pictures, so stay away from B&W conversion in the camera. That's a toy
function, invented by marketroids for appealing to novices.
