For this experiment we went out with our camera and tried to practice controlling the aperture in a photograph. i found it a very good exercise and learnt quite abit about aperture conpared to what i already knew. In this photo the aperture the aperture is high because the teddy is in focus and the background is not, if the aperture is a low one everything is mainly in focas, but if high you can change it to the background to be in focus or the foreground whilst changing the aperture a little.
