Analysis of a flashback

Butterfly effect flashback scene:-


This scene shows a very good example of a flashback. It makes it clear to the the viewer when the flashback is going on with a simple change of contrast. This is also what we are trying to achieve. When we go into our flashbacks we are going to change the contrast to black and white.
The flashbacks in this scene are done through the main main character having a fit. This then leads to the character seeing his life from a different perspective, viewing himself.
The flashbacks continue throughout the scene with 3 seconds, or less, intervals.
