Title: Couple at Coney Island
Date:1928
Photographer: Walker Evans

This black and white image is of street portraiture of s couple at Coney Island. The picture includes the backs of the couples, looking over a railing into the water. This is a good example of a long depth of field, for everything in the picture is in focus, opposed to just the couple. We can see the scenery in the background as clear as the foreground.
The scenery in the background isn’t quite as crisp as the couple but it isn’t really heavily blurred either. The background is more focused than in your short example.
