The light microscope is an indispensable tool in the study of living organisms. Most biologists are familiar with microscopes, perhaps being first introduced to the wonders of the world of small things at a very early age.

This review (re)-introduces the concepts of magnification, resolution, and contrast, and explores how they are intimately related and necessary for effective microscopy.
