SLR Camera

On the SLR camera the aperture worked by turning it left and right to open your lens and close it,


as your adjusting the focusing, your adjusting the background of the main picture for example, if you was taking a picture of someone and wanted the background to be clear, you will use the focus to make the background of the person more clearer.
As the shutter speed is pressed on your camera, it takes a shot based on the settings of the camera for example, how the aperture and focus is set on the camera. However, before taking the picture a red '+' and '-' may appear which will then mean the you may need to make some adjustments to the aperture of the focusing. When a green light appear's, you are then ready to capture the photo. If  the light is is -' there's too little light and if it '+' there's too much light.
This was a good experience for me to learn about the camera and how it works
