Countryside sketches - Depth of Field/ Aperture Game

I have an idea for the game, this will be a landscape of the countryside with a variety of features placed at differant areas.  There may be rolling hills in the background, a river, farms and trees in the middle section with flora in the foreground.

The aim of the game is to photograph the scene with a variety of different features in focus.  This demonstrates how to use the aperture to create varying depth of field effects.

The larger the aperture the shallower the field, this is beause the light is spread through a larger area, this makes the image less clear.

The smaller the aperture the deeper the field, the more levels that will be in focus.  This is because the light that travels through the aperture (hole) is concentrated.

A way to think of this is to imagine that you have a hose pipe.  The aperture is the width of the hose pipe and the light is the water.  If you have a narrow hose or a water gun, the spray will be concentrated and the target will be saturated.  The wider the hole, the greater the width of the spray, the target will be wet but not as soaking as some of the water will fall away from the object.
