The book “Elektroschutz in 132 Bildern” (Electrical Protection in 132 Pictures) was published in Vienna in the early 1900s by a Viennese physician named Stefan Jellinek (1878-1968, a founder of the Electro-Pathological Museum). The pictures are nice and direct and unambiguous; they teach, graphically, that the surest way to kill yourself with electricity is to form a complete path from source (usually the bright red arrow) to ground (the screened back, pink arrow). Arrowheads provide the path for current flow. (Photo by The Vienna Technical Museum)

This latest photo series by Anelia Loubser, a photographer in Cape Town, reminds us that even the simplest change in perspective can change how things look drastically. By selectively cropping and flipping the dark portraits in her “Alienation” series, Loubser makes basic human portraits look like creepy alien close-ups.

The “Dancing With Costica” series began when Australia-based photographer Jane Long decided to brush up on her retouching skills. After finding the Costica Acsinte Archive on Flickr, she became fascinated with the images and their subjects, wanting to bring them to life and give them a story.
