Under exposure in photography is when a photo is over exposed. So their is to much light being let into the photos so it is harder to see and the photo is bright.
Under exposed in photography means that the photo is too dark and not much light is being allowed into the photo and the object being left too dark so it is under exposed.
Depth of field is when the photo's background is blurred out and the object in front is in focus.
Depth of field edits.

Shutter speed.
Shutter speed is when you change the amount of time that the shutter is open for. Having a low shutter speed means that more light is getting in as the shutter is open for a longer time allowing more light to enter the photo.
​
Having a lower shutter speed allows less light to get in because the shutter is open for a lot less longer time than it is with a higher shutter speed.
