My place to post silly pictures and rants, even though I’m no longer a PhD-student.
Even if I do say so myself, that fire makes a very nice path in the air. It must be some combination of a circle with a parabola. How long was the exposure time?
The exposure time was something around one minute. The picture is the one with spirit, I also have a nice one where you used lampoil. And a movie :-). I'll email the links to you.
Exposure time: one SECOND, of course.
