Camera Technique

 shot length

by taking shots from different distances you can create different effects. in this photo you can only see the character  and there no insight into were he may be this is effective when the director is trying to conceal the wereabouts of the scene and can create suspense and tension.

 In this example the camera is slightly further back so you can see a little more of the background and can see that there is still nothing in the background and still no insight to were this scene is taking place. A director can sometimes use this effect to slowly reveal the backdrop and still offer focus to the main character in the shot.

In this shot you can see the full background which allows the audience to see exatcly what is happening. this shows everything which is occuring during the shot  and the audience can be shown a number of things.
