By changing the aperture in the lens, you can make the resulting picture have more of the picture in focus from near to far, or you can limit the picture’s focus in one place.
- At ƒ1.8, the focus point will be much more defined with things in front of and behind the subject becoming softer looking further from the subject they are. This is a very nice way to bring attention to the subject.
- At ƒ22, the focus will seem to be sharp from very close to the camera to pretty much infinity. This is great for giving a sense of the place you shot the image, or for including many people in the image and keeping everyone clearly in focus.

Below, is a contact sheet of photos that we took with varying shutter speeds.
My favourite photo from the shoot is the one below, which I have added a purple hue to, to enhance the colours and separate the blur. This is my favourite due to the fact that starting at the feet, you can make out exactly what you are looking at but as you go further up the image it becomes more abstract and unpredictable.
In the first edit I added a blur effect over the whole image as a layer, then removed what i wanted to be in focus and kept what I wanted to be blurred.
In the second edit I created a rectangular shape and filled it with colour. This is a simple yet effective edit.
In the third edit I copied the image and rotated the image on its side. I then used the paintbrush to make the photograph seem like it is fading away.
