When shooing long exposures - it's a hit or miss proposition. In a span of about a 20 minute fire show by the Boston Circus Guild I must have easily shot over 200 images.
I wasn't sure which ones to share - so I'm sharing my favorites!
Settings wise for most of the images I hovered around 2-3 seconds at f5.6 and ISO 200. Once I had my exposure and focus locked in, I used an intervalometer remote and set it to keep taking shots (so I can also enjoy the show).
