Three Pillars of Photography

• Aperture

  Aperture can be defined as the opening in a lens through which light passes to enter the camera. In photography, the “pupil” of your lens is called aperture. You can shrink or enlarge the size of the aperture to allow more or less light to reach your camera sensor.

• ISO

  ISO will simply brighten or darken a photo. As you increase your ISO number, your photos will grow brighter. However, raising your ISO has consequences. A photo taken at too high of an ISO will show a lot of grain, also known as noise, and might not be usable.

• Shutter Speed

  Shutter Speed is the length of time the camera shutter is open. It’s how long your camera spends taking a photo. If your shutter speed is long, moving subjects in your photo will appear blurred along the direction of motion. However, if you use an especially fast shutter speed, you can eliminate motion even from fast-moving objects, like birds in flight.
