Burn and Dodge

Using a photograph I took of an old truck, I wanted to see what the dodge and burn tools could really do.  I converted the picture to black and white and made the darks darker using the burn tool and the whites lighter by using the dodge tool.  This is the result that I got...

As you can see, the photo on the top is a fairly nice black and white photograph.  (Although there are a lot of gray tones.)  However, the one on the bottom has a much better contrast.  The contrast adds a great artistic quality to the photo, making it a lot more interesting to look at.
