Decide what you want to portray the rewinding of. For me it was a time when I cut my own bangs. Decide how you are going to act it out or represent it. Take plenty of photos because you will need about 30-40 usable ones for printing. If it is about yourself, you may want to consider having a friend take the photos for you. When my friend took the photos for me, I first tried acting it out at a normal speed while she shot it in "Sports mode." But, there were long pauses in-between groups of photos, so we ended up shooting it photo by photo while I acted it out in slow motion.
