Types of Shots

The film harnesses 2 shots mainly in the introduction, POV shots and Long shots.
The POV shots, used to show us what our subject is looking at, are important as it immerses us with the characters of the film, for example when 9 leans over the table to find the dead scientist on the ground, instead of just showing us from a different angle, the director shows it from 9's perspective to give us emotion with the shot, as our first reaction would be similar to 9 and we feel remorse for him. This shot is important as it reminds of the character of the scientist himself as he plays a role later on in the film with the plot explaining the existence of the fabricator (the main "villain" of the film) and the explanation of the purpose of these ragdolls.

The other shots 9 uses is extreme long shots, a shot used from a long distance away, usually at a low angle, again from the perspective of the height of a ragdoll. It emphasize how collasal the city really is compared to these small ragdolls as the buildings and rubble tower over in the shots, it also increases the feeling of how lonely we are with 9 in this world. Moreover as when the camera zooms out it just shows how much of the environment is still and dead. Through this the director makes the audience feel hopeless and worried for 9 which contrasts heavily with the emotions the first few shots into the film give us from the creation of 9, which is more hopeful.
Also all these shots the environment give us a further understanding of the environment from the director. Mainly we see a world that is completely destroyed, but you see elements of a western society, so we know it's earth that this is on. We see tanks, power lines, something to grasp on. But it also focuses on the world of death, there is nothing alive. However all of these things still shown from the doll's angle view, giving familiar things a dynamic new perspective. Everything in a shot has a history, "a beautiful junkyard" the lead artist would call it, but even though it doesn't hit the audience in the foreground, but all the elements of the background wrap together to bring out an amazing environment as a whole.
