What does the Pre-shot do?
A13 Pre-shot lets you compose the background you want to capture in an image, and then include yourself on the background you choose. First, compose the background the way you want, and then press the shutter release button. This displays a semi-transparent image of the background on the camera's monitor screen. Next, stand in front of the background you just shot and ask someone to compose the image to include you. At this time, the person can use the semi-transparent monitor screen image to compose the background as you want it. When he or she presses the shutter release button, your image is recorded against the background.

但都係唔得既? 有冇人識用?

[AFA]

u can photo the scene u want (scene with u inside the photo),
and after that, u can tell other ppl to follow the scene to take.
