Manual Camera
ISO determines how sensitive your camera sensor is to light. The darker that the environment you are shooting in, the higher that the ISO needs to be. Using the correct amount of light, ensures you have the right exposure. ISO is one of the three main pillars of photography. It’s part of the exposure triangle together with aperture and shutter speed.
Shutter speed
A camera takes a photograph by exposing a digital sensor to the light. The shutter is a barrier that keeps the light out when you aren’t not taking a photo. Pressing the button at the top of the camera which is called the shutter release opens the shutter, and when the shutter is open, an image is recorded and when the shutter closes, the camera stops recording.
APERTURE
An aperture is basically a hole inside the camera lens that gets smaller and bigger to let in more or less light. For example the pupil in your eye, the bigger your pupil is the more light is let in and the smaller your pupil is the less light is let in.
