Day 1- Overview
Shutter speed, aperture, and ISO affect and control the exposure of your photo. Grab your camera and become familiar with where to find these different settings and how to adjust them.
We will talk in later lessons about how shutter speed, aperture, and ISO relate and how to adjust them.
Here are some quick notes for the exposure triangle:
• This is found in the lens, not in the camera.
• When the aperture is wide open, it lets in a lot of light.
• Aperture is also referred to as f/stop. The higher the f/stop number, the smaller the opening and the less blur in the photo. The lower the f/stop number, the larger the opening and more blur in the photo.
• This also controls the depth of field (or amount of blur).
• Serveral professionals will shoot on just Aperture Priority because they are constantly changing their depth of field.
• The shutter is not in the lens, but in the camera.
• Short shutter = Virtually no motion blur
• Long shutter = Lots of motion blur
• This controls how sensitive the camera is to light.
• A higher ISO will bring in more light and make your camera more sensitive to light.
• A lower ISO will bring in less light and make your camera less sensitive to light.
• ISO helps compensate when changing the Aperture and Shutter Speed isn’t sufficient.
