The images above are a series of screenshots taken from some sci-fi/horror trailers. I have selected these shots as I think they would make my trailer look professional. As you can see several were taken from the trailer for Extraterrestrial, a sci-fi/thriller trailer based on invasion. I have explored different genres in order to get a wide range of ideas for my trailer. The main thing I like in the majority of these screenshots is the lighting used. As you can see the two largest images are only lit in the centre of the frame and even then it is difficult to see any detail. The bottom clip I particularly liek because the angle of the shot gives a foreboding sense that something scary is about to happen.

I also really like the CCTV effect as shown in the image from 'The Taking of Deborah Logan'. Although it is not a real cctv camera it gives the effect of being real. This is done in a similar program to after effects in order to get the cctv look.
