Does your picture have correct EXPOSURE? Exposure is the amount of light that falls on your sensor or film. 

Too much light and your picture will be overexposed, or washed out.


Too little light and your picture will be underexposed, or too dark.


There are three main factors that impact your exposure, aperture, shutter speed, and ISO. These have been called the exposure triangle. We will talk about what these are and how to use them below. Later this year, we'll look at how to break some of these rules.
