You set your camera to take black & white pictures, you take a picture, and you can view your picture in black & white. Then you can use photo manipulation software to modify your pictures. You can crop, sharpen, add effects or enlarge your picture using software like PhotoShop or Fireworks.
There is no recipes for what to capture, but you can add borders, frames, captions with text to make photo more interesting. Also you can tint photos, convert to black and white.
