Photography should be fun
Photography has many uses for business, science, art and pleasure. These photos are just for fun of it - means strictly pleasure 
. Photographers control the camera and lens to "expose" the light recording material (such as film) to the required amount of light to form a "latent image" (on film) or "raw file" (in digital cameras) blah blah blah.... Photographers may do that, me just the other way around camera controls me I just push the button.
