Hang Time

Many point-and-shoot digital cameras, and a number of digital SLR (single-lens reflex) cameras, suffer from something called shutter lag. A camera's lag time is the length of time from when the shutter release button is pressed to the time when the photograph is taken. A number of conditions affect lag time, but the general rule of thumb is that the more expensive a camera is, the less lag time it has.

Lag time will affect your timing, so you'll need to practice with a few shots and see how quickly the camera can respond (Figures 10.4a and 10.4b). Flash-charging time is a big factor in camera shutter lag (the camera can't take a flash picture until the strobe is charged), so adjusting to a faster shutter speed and turning off your strobe may help speed up your camera's response time.
