The Blackhawk Auto Museum in Danville, California, houses some of the world's most exotic and valuable cars. Each of them is maintained in pristine perfection. Photographing them is another story. The lights are hot and are wildly uneven in both color and brightness. The museum's "no tripod" rule dictates hand held exposures in the range of 1/10 sec. to 1/20 sec. @ 200 ISO. But the results are amazing from the Nikon D100 and D2x cameras.
