Inspired by this great shot, I set my precious tequila on fire. I wanted to have a completely black background.
I don't like, that the top of the flame is cut off. Could've corrected that in PS, but was too lazy :-)
One 430EX on the left and behind the glass, pointing away from the glass, fired against a white towel at 1/16 power at 50mm zoom. 25s exposure at f4.5.
