I've already told you about Nathan Webster, a Desert Storm Veteran, turned embedded photojournalist in Iraq.
I've mentioned that he is attempting to raise enough money to publish a limited number of quality books with the pictures he took in Iraq from 2007 to 2009. I'm going to let him tell you why. He has 3 weeks to go and is most of where he needs to be. The overall cost is small. The rewards for your pledge are at least as valuable as your contribution. The rewards for success are certainly greater than the overall cost.
And you can read his work daily here.
