I was investigating Aperture and Depth of field in photography and what they both do. Depth of field is the amount of distance between the nearest and farthest objects that appear in acceptably sharp focus in a photograph. This is commonly done by focusing on one object while the other surrounding objects stay out of focus. An aperture is a hole or an opening through which light travels (In this case, the sense) More specifically, the aperture and focal length of an optical system and determines the amount of light allowed to travel through and focus on an object.

Examples of ‘Depth Of Field’



Aperture Scale

Aperture 2

The aperture scale shows how much light is let in depending on the depth of field so a larger aperture (Which let’s more light in and has the most open lense) had a shallow depth of field (Focus) Whereas, a small aperture (Letting in the least amount of light in and has a small opening from the lense) had a deeper depth of field (Focus)

DSC_0060This image is an example of a deep depth of field shot. This means the foreground image is the main focus of the shot. The plant in the foreground can be seen in extreme detail whole the background is slightly blurred out and less focused. This means that less light was striking the image sensor.
DSC_0059This image is an example of a shallow depth of field shot. The background is more focused than the foreground object which is a plant almost like the camera is looking through it to focus on the background. This means that more light was striking the image sensor and brought more light in.
DSC_0043This is another example of a shallow depth of field shot with the background pen in focus while the foreground is blurred out. This means the light is focused on the background rather than the front.

DSC_0025 This example is a deep depth of field shot. The plant is being focused on letting minimal light in to the background meaning it focuses on the foreground plant.
