Camera Controls
There are three different controls on the camera and they all do different things to help you get the best possible photo you can gets. These controls are: ISO, shutter speed and aperture.
The ISO is how sensitive your camera is to light. The higher the ISO the greater the sensitivity, the lower the ISO the lower the camera is to light sensitivity.
100, 200, 400, 800, 1600, 3200.
The shutter speed controls how long the light will hit the sensor on your camera. if the shutter speed is fast it can completely freeze an image, but if the shutter speed is slow it can blur your image.
1s, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000.
The aperture controls the quantity of light let in. The lower the aperture the more exposer you get because more light gets in. The higher the aperture less is exposed because less light enters the camera.
The smaller the aperture, the greater depth of focus you will get.
