Exposure is something key in photography, there are three main things to do with exposure.
Underexposed | It's where an image is darker than normal and some lighter detail in the photo is lost, this is useful for when shooting in bright areas.
Overexposed | It's where an image is lighter than normal and some darker detail in the photo is lost, this is useful for when shooting in darker areas.
Correctly Exposed | This is the exact middle between overexposed and underexposed, it is bright\dark enough to see a normal amount of detail in the picture.

The exposure triangle
- Imagine your camera is like a window with shutters that open and close.
- Aperture is the size of the window. If it’s bigger more light gets through and the room is brighter.
- Shutter Speed is the amount of time that the shutters of the window are open. The longer you leave them open the more that comes in.
- Now imagine that you’re inside the room and are wearing sunglasses (hopefully this isn’t too much of a stretch). Your eyes become desensitized to the light that comes in (it’s like a low ISO).
