For this photo, I moistened the glass for the older-used, shiny look and set brightest light source in background to capture smoke ring. Two smaller light sources behind, one to my right and the smallest over my left shoulder provided light necessary to see the front and reflect off the water bubbles. To give it an older feel, I applied a grainy filter.
I used an iPhone 4S to take the photo just after extinguishing the flame. I prefer using a digital SLR with big lens, but have been giving the phone a try.
