In order to create Henry's fake wound we used:
Red food colouring
We wanted Henry to look as if he has just been murdered which is why we decided to splatter the 'Blood' down his arm and also why his eyes are closed and he is draped awkwardly over the sofa.
These where some of the different camera angles we chose to film at to get the best possible result from our filming time. As we only had 3 hours, including the time we had to create the wound we needed to work quickly so discussing these camera angles where done whilst other things where being sorted out. The 3 of us all helped with the preparation and set-up of the set and this saved a lot of time.
This was an action shot of us setting up and Henry testing out the positioning on the sofa to see what the best angle would be.
