What is depth of field?
As a result, depth of field (DoF) is the distance between the nearest and furthest elements in a scene that appear to be “acceptably sharp” in an image. The distance between the camera and the first element that is considered to be acceptably sharp is called DoF near limit. The f-stops work as inverse values, such that a small f/number (say f/2.8) corresponds to a larger or wider aperture size, which results in a shallow depth of field; conversely a large f/number (say f/16) results in a smaller or narrower aperture size and therefore a deeper depth of field.
To get a deep depth of field your f-stop would be about f/5.6, f/ 4.8 and if you want a shallow depth of field, your depth of field would be about f/18, f/20

These Images were taken with a shallow depth of feild with an f stop of about f4.5/5
These images were taken with a medium depth of feild with an f stop of about f16.
These images were taken with a deep depth of field and with an f stop of about f22.
My best image is the one on the left because I like how the flower is in focus and you have a blurry background. Whereas, the image on the right is my worst one because the actual picture is blurry and it's overly exposed.
Here are some other images which show depth of field
