Editing A Shot With Effects

This screen print is of me editing my music video by adding in a shot of myself walking past the camera, which I clipped onto the side of a door by using the clamp tripod. From using this piece of equipment I have managed to get the effect of a CCTV image by framing the camera in this way and also by using a canted angled shot. I then desaturated the shot so it was in black and white to make the effect more realistic and also to reflect the mood and feel of the music video. I also wanted to make the image a bit fuzzy and less sharp to try and get the effect of a CCTV camera but I am unsure how to do this so I will research this.
