There are three things needed in order to capture the right amount of exposure. The exposure is determined by three things; aperture, shutter speed, and ISO. The aperture is the size of the opening of the lens. The bigger the aperture the more light will come in and the smaller the aperture size the less light will come in. The larger the number is the smaller the aperture size is, and vice versa the smaller the number is the bigger the aperture size is. The depth of field will determine how much of the image is in focus. The shutter speed will determine the length of the exposure The longer the shutter speed the more light comes in and the shorter the shutter speed the less light comes in. The shutter speed determines the blur in the image. The longer the exposure the more blur there will be. The ISO is the sensitivity of the sensor to light. If the ISO is low it means that it is less sensitive so it would need more light to take an image. If the ISO is high it means that it is more sensitive so it requires less light but, it will add more noise to the picture. Noise will saturate the picture making it look less realistic.
