Digital photography at very small apertures can actually reduce the quality of your images. This effect is explained here in detail.

Lens aperture and diffraction. Nikon D5100 due pixel size 4.8 µm above f11 starts to show difraction, while Nikon D4 with pixel 7.3 µm shows difraction above f16.

Lens Diffraction & Photography. Photo: airy disk with rings. "For an ideal circular aperture, the 2-D diffraction pattern is called an 'airy disk,' after its discoverer George Airy. The width of the airy disk is used to define the theoretical maximum resolution for an optical system (defined as the diameter of the first dark circle)." http://www.cambridgeincolour.com/tutorials/diffraction-photography.htm#calculator
