The document discusses common camera techniques used in slasher film posters, trailers, and films. It notes that low angle shots are typically used to emphasize the antagonist, making them appear threatening. In contrast, high angle shots are used for victims to portray them as weak. Wide shots and pans are used to establish isolated settings. The document then discusses how the filmmaker will apply these techniques in their own slasher film trailer and posters, including using low and high angles, long shots, and close-ups to portray characters and generate fear.
