For the typical compact camera flash, the flash duration is between 1/200 second at full power and 1/20,000 at the lowest output level. That sounds fast but when I add some diffusion to the flash - like a small softbox - I end up having to use the flash at, or very close to, full power. That just left some subjects still a little blurry.
Dragging The Shutter
One of the techniques we covered was a creative strategy that involves “dragging” the shutter when taking a flash exposure. Dragging the shutter is really just a fancy term for using a long shutter speed and it’s generally a technique used in location lighting and not the studio. But we’re creative and there is not right way or wrong way here so let’s get started.
