Sampling, before I began filming I wanted to test to see if the green suit would would within the forest. I'm really glad I did this due to me forgetting that the forest was green!! The reason this was a huge problem was because I wanted my enemy's to be invisible this meant I had to get rid of the green suit in post-production. Now the keying effect in after effects requires the subject to be a certain colour hence why I had my brother wearing the fully coloured green suit. However after coming back from the day of filming I realised when trying to key out the green suit it was also picking up the greens from within the forest. So I then ordered a blue suit (see below). This worked a lot better within the forest however I never used the clips in the final trailer due to the clips not being very good. However this is a prime example as to why I under went sampling for my project.
