This first image is a High Key image of Jay Street. You can tell it is a High Key image because of how bright it is. you can clearly see how the sun is shining bright on the edges of the building. You can tell the sun is on the left by looking at the huge shadow the building created on the street. By making this image gray scale, it made the street looks sad and depressing. You can only see a few cars drawing by which people can take as this part of town is really dull and boring.
This second image is a Low Key image of a computer with the screen on in a dark room. You can tell this is a Low Key image by all the negative space. There is no shadow in this picture only a little highlight on the keyboard caused by the brightness on the screen. Part of the keyboard is light and the rest faded into the darkness. This picture can represent there will always be light in the darkness.
