Microscopy remains one of the few areas of science in which enthusiastic amateurs can make others take notice. Nonprofessionals routinely produce stunning images of creatures and objects too tiny for the eye to resolve. This crowdsourcing of microscopic imagery arrived long before the invention of the smartphone and networked communications: the amateur has long made a mark with the microscope—in the early years, by hand drawing images that appeared underneath the lens, and, in more recent times, with the added realism brought by the photograph.
