SA Science Lens has maintained three consistent categories each year, namely; Science as Art that illustrates the beauty of science or shows natural subjects in abstract ways; Science in Action that capture sciences at it happen; and Science Close-ups that reveal aspects of science that cannot be seen with the naked eye. Each round has an additional category, or categories, which vary from year to year. Participants will select an object or action of their choice that communicates science in the categories. The entries, that includes the photograph, as well as a description of the photograph, which must communicate something about the science or work of a scientist, are then submitted. An appointed panel then judges the entries.
