I just found this picture I took 6 years ago. I was at the Cleveland Air Show and was using my Canon 5D Mark II and 70-200mm f2.8 with monopod. The sky was obviously not that dark (edited with Photoshop) but the overcast sky is what allowed me to get the shot.
Really nice shot, Gage. Your choice of PS effects is very dramatic. Great job!
Thanks Mark!
