The first thing we learnt about was the exposure triangle. The exposure triangle is built up of three camera settings: shutter speed; apeture; and ISO. All these things control how light the shot will be. However, they also effect other things within the camera.
Shutter speed: this is the time it takes for the lens to open and close in a picture. The longer it takes, the more blurry it will be because of the motion blur. This also applies to film but it is mechanical, and the camera does it instead of the shutter actually closing.
ISO: This changes how sensitive the sensor is to the light. The higher the ISO the more light there is. However, it also adds grain to the image.
Aperture: This is how big or small the apature or iris is within the camera, controlling how much light is let in. It also changes the depth of field. The lower the f. the shallower the shot is.
We went out and did our examples.
We went on http://canonoutsideofauto.ca/play/ and played around with the settings.
We were set the task to create certain images.
Image with deep depth of field on 1/90th shutter speed:
Shallow depth of feild at 1/90th shutter speed:
Deep depth of field with 1/45th shutter speed:
shallow depth of field with 1/24th shutter speed:
Examples from professional films
An example of a shallow depth of field is Inside Llewyn Davis (2013), Directed by The Coen Brothers.
For this shot they have used a very small apature number, meaning that the apature ring is large. Making it a shallow depth of field.
Another example of shallow depth of field is Fish Tank (2008) Directed by: Andrea Arnold. They’ve done this shot to isolate her and show that the shot and film revolves around her.
Deep Depth of Field
This is an example of deep depth of field in the film The Revenant by Alejandro Iñárritu. The depth is used in this shot to create distance, and show how big the space in they are. This creates an aspect of loneliness and how far away they are from anything else.
