Hd On Canon Gl1 How Do I Shoot In Black & White On My Canon HG21 HD Camcorder?

How do I shoot in black & white on my Canon HG21 HD camcorder? - hd on canon gl1

Do I have the opportunity to influence black and white, that the screen goes black and white, but the second release of the record changes in the color?

Ideas?

Thank you guys.
