Research on flashbacks

Techniques For Formatting a Flashback To determine where a flashback is needed in the script, the screenwriter should decide when the audience needs to know something from the character's past. Getting into the flashback scene (transitioning) is just as important as the flashback scene itself. Transitions must be executed smoothly and seamlessly so that the audience is not jolted from the present to the past, and back again to the present. To smoothly transition into a flashback from a present-time scene, you can use techniques that evoke the protagonist's memory. He can look at a photograph that carries him back in time. He can gaze at a lake or mountain that carries him back to a similar setting in his past. Or he can hear a melody that evokes a memory of a past time. Sourced From Google
