This is familiar territory for photographer Jannicke Wiik-Nielsen. Her portraits of insects, parasites, bacteria, and other exceptionally small life—part of a collection dubbed Hidden World—showcase these creatures in ways that make them look less like “creepy crawlies,” as she calls them, and more like characters. She achieves the effect through scanning electron microscopy, a technique that yields high-resolution images through the use of electrons instead of photons.
