adjust your monitor to black and white? LOL.. come on man.. all software that comes with your camera should be able to do that. You can change the saturation level to the lowest setting.
Ey whats going on Luka.
Making a picture black and white is real simple. Can pretty much always be done on the camera. Just check out your camera and search around for the "effects" section, and select Black and White (B&W).
If not, open your image with any photo editing program and you'll easily be able to convert your image from colour to black and white.
I noticed you were by Dundas Square. Just for having a pic in Toronto, I fixed it up and made it b&w:
