Assignment 1
Below is a series of images showing the results when the aperture is gradually reduced in size. The brandy bottle remains in focus throughout the sequence, but as the f stops go up (meaning the aperture becomes smaller) the background becomes more prominent. This is because the depth of field is increasing as the aperture becomes smaller. All the images in the sequence where taken with a 70-300mm lens, with a focal distance of 82mm, this helped to create a more shallow depth of field due to the narrow field of view. The shutter speed had to be increased as the aperture was made smaller to allow the image to be correctly exposed.
Assignment 2 - Foreground to Background
The following series of images demonstrate the effects of a large depth of field, with everything within the frame being in focus.This effect was achieved by using a smaller aperture and positioning the camera further away from the subject.

| f/22.0 1/8 ISO 100 |
Assignment 3 - Foreground V's Background
The following series of images is intended to display the effects of using a shallow depth of field to demonstrate a visual hierarchy. The images were shot using a 35mm fixed focal lens which allowed me to use a wide open aperture for all of the following images.

| f/2.0 1/160 ISO 100 |

| f/2.0 1/160 ISO 100 |

| f/2.0 1/500 ISO 100 |

| f/2.0 1/1250 ISO 100 |
 |
| f/2.0 1/1250 ISO 100 |
 |
| f/2.0 1/1250 ISO 100 |
 |
| f/2.0 1/800 ISO 100 |
Assignment 4 - Shallow
The next two series of images displayed are examples of selective focusing whilst using a shallow depth of field. This allowed me to isolate individual subjects whilst the remainder of the image was out of focus. To achieve this result the aperture was left wide open (a 35mm fixed focal lens gave me a more shallow depth of field because of the larger maximum aperture) and I remained approx 0.3m from the subject.
