- This video covered the basics of photography

- There are three things that change the exposure in a picture

- The exposure of a picture can make a picture either bad or good

- The three things are aperture, shutter speed, and ISO

- There must be a balance between these three things 

- The aperture affects the amount of light that comes into the sensor

- The aperture also affects the depth of the field

- The depth of the field affects the focus of the picture

- The shutter speed determines the length of the exposure

- The shutter speed also determines how much blur there is

- The ISO affects the sensitivity of the sensor to the light
