High key is when the color white dominates most of the image. I only took 3 pictures that correctly define high key. The first picture was when I looked up and the stairs were white  so I captured that. The second picture was of a drawing of a boy in a case on the wall. It was done in pencil and the paper was white therefore the dominant color was white. The third high key picture was of the blinds. It was mostly white and light gray because of each thin line in the blinds . Low Key is when black dominates most of an image. I took two low key pictures. One was of a light that was fairly bright that it made everything around it dark look dark even though it wasn’t. The double doors in the staircase was the second picture because they’re black doors with small windows.
