If you guys like steam train photos, look up O. Winston Link. He may well be my favorite photographer. He photographed steam trains at night using huge banks of flash bulbs. This is probably his most famous.
He used 42 #2 flash bulbs to take this picture. As I recall from my camera store days, a #2 flash bulb was about the size and shape of a 75 watt incandescent bulb. It even had a medium screw base just like a bulb you would use in your hose.
