Spontaneous Combustion

@Francis: No, it is not a double-exposure. What you see is exactly as I shot it in real time.

@Carol: I don't want to say too much about what was happening (or happened) except that it took some time to position myself in the exact position to capture this shot as it occurred. :-) If you disect the image closely you might be able to conclude how the event took place. :-)

@Carol: No reflection. :-) The shot was straight ahead with no tricks of light or mirrors.
