  • Aperture
  • Shutter Speed

The Aperture

The aperture is in a camera as it controls how much light enter the camera through the lens. It is like the human eye as it controls how much light you want to let it. The bigger the aperture the more depth in field and the smaller the aperture the less depth in field. The value of aperture is measured with a f number the higher the f number the smaller the hole is and doesn’t let much light in, whereas the lower the f number the bigger the hole meaning there’s more light that has been let into the hole.

Shutter Speed

In most of the film cameras, the shutter is placed right in front of the photo film to avoid any unwanted exposure to the light. The shutter is made up of several blades that are in front of the lens. When you push the shutter, it releases a button which makes the blades open up and which exposes the negative film to the light. You can control the shutter speed yourself from 30 seconds to 1/4000 seconds. The longer the shutter speed the more chance motion blur would occur as these type of camera are really sensitive.
