The image is captured using the flash output setting you established in Step 3.
Flash exposure lock is also helpful when you're shooting portraits. The pre-flash sometimes causes people to blink, which means that with normal flash shooting, in which the actual flash and exposure occur immediately after the preflash, their eyes are closed at the exact moment of the exposure. With flash exposure lock, you can fire the preflash and then wait a second or two for the subject's eyes to recover before you take the actual picture.
Better yet, the flash exposure setting remains in force for about 15 seconds, meaning that you can shoot a series of images using the same flash setting without firing another preflash at all.
