Editing In Memento

In Memento the editing is very fragmented and not in order, this shows how the life of Leonard Shelby is all muddled up this shows how Leonard makes sense of his life with short term memory loss.
The First scene we See is when Leonard is holding and waving a photo in the air, and the start we do not realise what he is doing but then we realise that the shot is actually being shown backwards and we see that he has taken a picture and it's actually being developed in reverse, this edit allows us to see that Leonard's life is all mixed up and confusing to him.
In the shots where Leonard's life is being shown in black and white we can see fast paced editing which shows close ups to certain parts of the room like reminder notes, the closeups allow us to see what they are and how unfamiliar they are to the main character, all the small notes are symbolic to Leonard  because of his memory problem, he can gain insight from what he See's written on them .
The first scene that is shot in black and white is just after the scene were we see Leonard kill someone, the kill scene is shot entirely backwards this gives us the ending at the start of the film, but we have no idea how it got up to this point, this hooks us instantly, we want to know why Leonard kills this man.

The next scene is in black and white and is shot In the right way round, we can tell that it is in a different time frame, as he seems to be back in a hotel room that he has been in before but can't quite remember. The dialogue that we get is his own subconscious as we can hear that he is constantly reassuring himself as to what he is doing there, he finds it hard to determine what time period that he has been in the room, this is the point where we can tell that he has a memory problem. In this scene we know that he is unsure about himself and has to try and make sense of his surroundings. He is wearing a dressing gown so we know that he has been there for a while but we are not told any more information about it.

The next scene shoots back to colour and we see him interacting with the motel assistant, though we can't tell what he is saying, the camera then jumps to a close up of someone coming through the door, we know that this person is familiar to him as he calls he by a nick name, the camera cuts back to Leonard so we can see his facial expression.
