Exposure Triangle
The main ingredient that makes a picture sweet is the quality of light that we use in creating the image. when we talk about the quality of light, we talk about the source of the light and the temperature of the light. The basic fundamental components of how light is controlled in our image are three. They are Aperture, Shutter Speed and ISO. Lets start with SHutter Speed. The shutter is a curtain that sits right in front of the sensor to shield it from light. By doing this, it also helps the photographer to control the amount of light that hits the sensor per time. So, when the shutter button is pressed, a series of reflex actions happen in the camera and that includes the shutter opening and closing at intervals. the speed at which the shutter opens and closes is what we call shutter speed.
