Depth of Perception Test

I completed a series of photographs that helped me understand and come to terms with how the increase and decrease of aperture can affect the depth of perception within photographs depending on the type of picture or narrative you want to capture.

This image was created using the AV so that i could focus all my attention of the aperture and let the camera configure the shutter speed.

I chose to use f/14, as the picture is in a medium shot and only needed a small space to focus on - the background.

Similar to the last image, I created this using the AV mode so that I could focus on the aperture.

For this, I set the camera at f/7.1 - shallower than the last one - as I was aiming for a smaller area to focus on - the person. However, I feel like the lighting makes the image look out of focus slightly as well as the window background which may make the viewer question whether or not the person in focus.

Everything in focus

This image i created using the aperture focused setting - AV.

I set the aperture at f/20 as this meant that the camera would be able to keep everything in the image within focus. Personally, I feel like this image shows that quite well - blends the previous two pictures together.

Face in Focus

I created this image using the AV mode - for the aperture setting.

On the camera, I set the aperture at f/5.6. I set it at this depth because whilst it was enough focus on the face, it was able to keep the whole face in focus whilst the finger - which is quite close - can be shown out of focus.

Finger in Focus

This shot was also created in the AV settings mode to allow me to control the aperture.

The aperture for this shot was f/5.6. Similar to the picture before it, as it created the same depth of field i was aiming for. However, in contrast to the other image, the focus of this shot was on the finger and the hand.

Coins

For the next group of pictures, I placed some coins on a flat surface diagonal from one another. I then placed the camera within 30cm of the coins and tried to use the depth of field and focus to help create the effect that the coins were disappearing into the distance.

For all of these next shots, i used the AV mode and set the shutter speed at f/5.6, as this helped me to focus on a smaller area and put the background out of focus, as was the exercise within this workshop.
