Guerry, there was no playing with depth of field, I was shooting under heat lamps, during service. I was wide open, f1.8, hand held, shutter speed was around 1/250. I had anywhere from 60 to 90 seconds to frame and shoot. Prior to service, I used a bag of chips to set up my camera. I found that shooting from about 24" was the best setup, out to 30" if need be. I wanted to shoot as close to full frame as I could. One of the beauties of what I did, was that with the short shutter speed and strong top lighting, the background blurred and darkened.
Back when I shot football games for newspapers, I learned that zoom lenses are great fun, but, having a camera and lens combination that I knew performed in a certain way, at a certain distance, I found I could frame fast. Fixed focal length is always my go to when I will not have time to fuss.
me: I don't drink anymore
Yelonutz: me either, but, then again, I don't drink any less
