About aperture
The aperture is the opening in the lens that lets light into the device, and changing the
aperture controls the amount of light that enters. More light enters when the aperture value
is smaller, and less light when the aperture value is larger.
Small aperture value Large aperture value
About shutter speed
The shutter speed is the time that the shutter is open. Slow shutter speeds allow more
light in, but moving subjects may blur. Faster shutter speeds allow less light in, but moving
subjects are sharper.
Slow shutter speed Fast shutter speed
