Aperture
Aperture also known as ‘F Stop’ controls the light and how in focus the image is this is also called “depth of field”.
The higher the F Stop the smaller the aperture therefore less light is let through and the image will be in a higher focus.
The lower the F Stop the more light will be let through and the less in focus the image will be .
For the first task I arranged 3 objects onto the desk and took two styles of images.
The first images had a high F Stop around 13 therefore all 3 objects were in focus.
The second set of images had a much lower F Stop around 3.5 therefore only the front objects were in sharp focus and the background was blurred.
Next I used the same techniques on photos of people. I found this to be much harder as you needed to be close to the subject but still have a lot going on in the background to get the desired effect.
The first set of images I took had a higher F Stop at around 14 therefore the person and the background was in focus.
Then I set the camera to a lower F Stop around 4.5 therefore the person was more in focus and the background was blurred.
The last set of images I took had a much higher F Stop at 22, however I found with these images the higher F Stop made the pictures blurred, which I learned may be because the shutter speed is too slow to handle that high of an F Stop.
I tried the aperture task again. Here you can see the contrast in the background between the two images. Using the lower F Stop you can see the objects in the background are less in focus whereas the person is sharp. Using the higher F Stop you can see the background objects are more in focus but I found this made the person less sharp.
F Stop 4.5 
F Stop 14
I used the aperture technique on pictures of food to practice, I found that controlling the aperture was easier on objects than people this may because you can have more control of where they are situated and they do not move.
Here I used a low F Stop 3.5 to achieve the food at the front being in focus while the background was blurred
Then I used a higher F Stop at around 18 I aimed for the whole image to be in focus however I found that the closer objects became blurred and the background was in focus using this aperture setting.
