Light writing involves moving a light source in the dark while the camera shutter is open for a long exposure, creating trails of light. Using a slow shutter speed, small aperture, and low ISO allows the background to appear black while the light trails are visible. Out of focus images are created by adjusting the camera lens until the subject is blurred, which works well with light sources as it turns them into circles of light. Changing aperture, shutter speed, and ISO can also produce blurring effects.

2. Light Writing
Light writing is achieved by using a torch or any light source and moving it about with your camera on a long shutter speed so the light
creates a path. It is best to do this in the dark so you can clearly see the light and the camera does not absorb too much light to make the
image too bright like the image on the right. The camera needs to let in as little light as possible to make sure the background is black and
you can just see the trail of light.
The settings I used for the left image are:
Shutter speed – 4
Aperture – F11
ISO – 200
Zoom – 18mm
The settings I used for the right image are:
Shutter speed – 3
Aperture – F3.5
ISO – 800
Zoom – 18mm

3. Out of Focus
Out of focus images are taken by altering the lens barrel on the camera until the area you are pointing your camera at is blurry. This works well
with lights as it makes them look like circles of light. The image look quite abstract as you can only tell what the light source is as everything
else is blurry. Changing the camera settings like the aperture and ISO settings will also help with the blur/out of focus effect which is what I
have experimented with. You just have to alter the lens barrel until the view is out of focus and you cant really tell what it is. It think if there is
a light source it is best to completely blur out everything else because the lights look good out of focus.
