Week 82, Assignment 2 for Take A Class With Dave and Dave.
Nails. Another great stock image can come up here. Don't be constrained. However... for those who dare, I think if you can create the motion blur image of a hammer hitting a nail, and you nail it, then tag with "money" and move to the head of the class. I think this will be a challenging shot, and not for the faint of heart. After your subject has swung the hammer 50 times you might want to bail out to the nearest Vietnamese nail shop.
One of the nice features about the Canon 580 EX II is the multi-flash setting. It took a few tries to get the setting just right, but I eventually got it.
I also did an alternate "nail" shot in case this one didn't work out.
