Monochrome photography is where the image is produced in one colour or shade of one colour. Monochrome images in a neutral colours are also known as gray scale or black-and-white. Personally I believe these type of effects gives the image a stronger feel.
This is an image i took of an abandoned room. There are four staggered chairs, a table with a hot drinks cup on it. the room is illuminated by the light coming in from the window located behind it. It images seem to focus of the room itself. The image is taken from the aspect of the door, as if you were walking past it and noticed something. It seems as if whoever was in the room was interrupted by something that happened outside the room. One of the chairs is facing towards the window, maybe whoever was sat there may have noticed something outside the window.
