This is a good game for paying attention to the details in nature.  

Here you need groups of twos.  One is the photographer and the other is the camera.  The camera lens – or the eyes _ is closed.  The photographer leads his camera to an object, positions it either close to the object or a little farther away.  When the camera is in position, the photographer pulls gently on the earlobe of his camera who then opens his eyes and the photograph is taken.  Then they go on to the next object.  After two of three pictures, they change roles.
