CCTV effect

I wanted to give the effect that at all times, these girls are being watched or investigated leading up tot the attack. by zooming in and putting an effect on the shot it can give the effect of a CCTV camera. i put the effect so that there was a black and whit wash on it then i turned the contrast up which made it very effective. the shot them becomes less clear however as you can see in this real life CCTV, its blurry therefore conforming to the look of a real camera.
This also then helps to add the effect that there is a reason or plan behind what is happening which allows the audience to want to watch the rest of the film as they want to know why the girls were targeted.
