Editing.

I then included a fade and place the shot where the main character is looking up the stairs with curiosity, this is the mid shot of her. It then zooms in slowly - which I did with the camera itself, and then changes shots.
The second shot is her still looking up the stairs but is a high angle shot as I want the audience to feel that she is feeling vulnerable at this stage. Whilst shooting this shot I zoomed into the characters face to show the emotion more clearly. When editing this scene into my trailer, I used the speed feature in Pinnacle to speed up the zoom. I feel that this gave the shot a sense of awkwardness in which i want the audience to feel uncomfortable.
Along with the zoom, I also added an old style film effect, as this looked more authentic to the picture/scene.
