I want to take some photographs of balls of natural gas being lit by a match. I can easily make the balls of gas with washing detergent and some natural gas, but Im unsure about how I could capture them on film . I would like to have a completely black background with only the fire seen, so what kind of lighting should I use? Would the flames themselves provide enough light in a almost completely dark room? Also what aperture setting would be best for such a speedy event? I have a Panasonic Lumix DMC-FZ15 digital camera, I have access to 35mm film cameras. Also I was thinking of trying to film the event digitally and getting one frame out of the movie for the photo. Would that work, or would the quality be horribly lacking? Thanks.
