Using the main settings of your camera such as aperture and shutter speed can make a difference to the way your photographs appear, thus helping your compositions.
Depth of Field, influenced by aperture and focal length can be used to make your
subject stand out by blurring the background or can be used to make more of your image in focus, from the foreground until the horizon.
Shutter speed can be used to either freeze moving subjects or emphasize their movement by allowing them to blur – both are great options for creating dynamic images.
By employing these techniques, you can be aware of what areas of your photograph will be sharp or blurry, and position them within your frame to your liking.
