Films in the media use many camera shots, angles and movement to interest the audience and create diversity throughout the movie. In Perks of Being a Wallflower, there are two scenes which particularly show a range of camera shots and angles, all used very effectively.
High angle
Close-up shot
Tilted angle
Over-the-shoulder shot
Extreme close-up
Long shot
Aerial angle
Wide shot
I think the most effective shots out of the above are the tilted angle and the over-the-shoulder shot. The titled angle because it gives a sense of the hysteria that the character (Charlie) is feeling; his mind is distorted, as is the camera. The over-the-shoulder shot is also effective because we can see exactly what is in Charlie's eyeline, and we get an idea of what he must be feeling. The fact that the shot focuses on a knife is disturbing and shocking.
