For the more daring, you can actually set up most digital cameras to capture black and white images. Check your owner's guide for selecting colors usually used to tint your photos. This can usually be found using one of the "creative" modes using full or partial manual settings (M, AV, TV, P etc.). Then use your function window to find the one that allows you to set color filters and BW settings.
