Oshkosh AirVentrure Night-Show, 2010

In 2010 the organizers of the EAA's AirVenture added a night-show on Saturday. This is a photo of Bob Carlton in his jet-powered glider.

Getting shots like this is kind of hit-and-miss. In this case I was shooting with ISO 1600, my lens wide-open, and a shutter-speed of 1/4 second. Panning with that long a shutter-speed is really more luck than skill. Setting the exposure is also tough. Many people simply use manual-exposure and set the aperture and shutter-speed after looking at a few test shots. The trick is trying to get the plane exposed enough to be seen, while not completely over-exposing the (very bright) pyrotechnics. Because there was a fairly wide range of brightness during the acts, I was using aperture-priority auto-exposure with -2/3 stop exposure bias.
