Codes and conventions is something I learned a long time a go in BTEC ND Media. Just because it is a basic knowledge, it doesn’t make it any less important. The best example of of codes and conventions is western movies. The antagonist wears black and the protagonist wears white. It’s simple but incredibly effective in terms of audience consumption. In my small experimental film, I want to use a black background for the subconscious and a white background for the conscious. It’s the same technique really, black is bad and white is good.
