What is Aperture?
The aperture of a lens is the diameter of the lens opening; the aperture is like a pupil. You can control the aperture by setting the "Aperture Opening", also known as an F-Stop. The smaller the F-stop numbers the larger the opening is and that allows more light in. A small aperture increases depth of field so foreground and background are sharp and a large aperture decreases depth of field so the background is soft.
What is shutter speed?
Shutter speed determines how long the shutter stays open; the longer exposures (like 1 second) give much more light to the film than a 1/1000 of a second exposure. A fast shutter speed can freeze action while slow speed can blur your image.
How do you shoot in each mode on your camera?
For Aperture I turn the scroll wheel to A and adjust the F-stops. For Shutter speed I turn the scroll wheel to S and adjust how fast or slow I want the speed.
