Mastering Exposure 2.0

Photography

During this week's lecture, we are exposed to 3 ways in mastering exposure / brightness.

Aperture

is the iris of the camera that controls the amount of light to enter the camera lens. The smaller the f-stop, the wider the diameter of the aperture. This allows more light to enter, hence producing a brighter photo.

Shutter Speed

is the time taken for the shutter to open and close. The faster the shutter speed, the darker the photo is as less light gets to enter in time. A fast shutter speed is used to take sharp photos of moving objects as to freeze them in the frame. A slow shutter speed however is used to create a bokeh effect photo and a light trail.

ISO

is the sensitivity of the camera sensor towards natural lighting. The higher the ISO value, the brighter a photo will be. ISO is usually the last resort to brighten the photo when all attempts failed. However, a higher ISO value can affect the quality of the photo produced (grainy).
