Shot/Reverse Shot | Screen Direction | Rule of Change | Murch's Rules
Basic Understanding:
Whenever your making a cut it is important to realize where your viewers center of focus is on the previous shot. If possible you want the focus of the next shot to be in a similar place. This will make for a smooth transition from one shot to the next.
Alternatively, if you want to cause an uncomfortable feeling to your audience or jar them on a cut you simply have to make sure that the images don't match graphically.
Example One
The bone thrown by the ape in 2001: A Space Odyssey becomes a space station. This cut helped to make the transition from the past Neanderthal world to the future 2001 (which is now our past). This cut juxtaposes the past and the present, yet links the two smoothly through a graphic match.
Example Two
A strong powerful cut. In this example we see the water draining away as the shot slowly becomes the victims eye, lifeless.
