After my feedback from my testing I looked back to what I really wanted to do with this piece. I was not happy of the grading of my film. It just made the footage look darker than it needed to be and it was hard to see colours that separated the sequences. I found this tutorial on making your footage old:
This was a great help showing a more convincing way to make my footage look like it had been taken on a 16mm camera. I wanted this style because of the Plus Guest piece I posted earlier. This has enabled the colour filters I put on the footage to be a lot more visible, plus they also work as vignettes on tablets.
