Chapter 5- experimental video

For my experimantal video i want to have two people walking up a hill to signify going up in life and the happy times people go through. I also what to have flashbacks of happy people and them having a good time. This will be in colour and i want it to be sunny. For coming down the hill i want it in black and white and to show the bad times in life and show flashbacks of bad times of things like arguing or falling outs.
