Canon PowerShot G12, Slow Synchro

One problem when shooting with a flash in low light is that often there will be a large discrepancy between your subject, which is well lit from the flash, and the background, which sinks into black. The Slow Synchro feature provides a way to light the foreground and background in the same shot (Figure 8.8). The flash fires briefly at the start of the shot to get a better meter reading of the scene. Next, the shutter opens to allow in enough light to expose the background. Finally, the flash fires again to freeze your subject in focus. The catch with Slow Synchro is that the subject needs to remain still during the exposure to prevent motion blur. (So that pretty much rules out toddlers for this feature.)

This shot was taken during the same session as those in Figures 8.6 and 8.7, but this time I enabled the Slow Synchro mode. The shutter stays open longer to gather light, and then the flash fires to freeze the subject in focus.
