Thanks for the vote! It was 114 degrees and this was my last shot. We chased the train, got a head of it and stood in the desert in the middle of no where for as long as we could - then back to Parker, AZ to catch the next train coming in. What you're seeing is white hot off the mountains -very dusty looking. My digital did not like that heat and I adjusted the light as dark as I could get it. Any suggetions for shooting in that kind of light and heat would be appreciated.
