One subject repeating itself several times in one frame is achievable through a simple technique called ‘multiple exposure’. Expose one frame several times, so that the main subject is in different positions in your frame. Calculate the total exposure required for a scene, and the number of times you need to expose it to determine the exposure for each frame.
For instance, if you plan to expose one scene thrice, then the exposure for each frame will need to be one-third of the total exposure needed. Use this technique to shoot people, make abstracts or even create a striking visual story.
