In Oko Erin, Nigeria, an indoor scene on a light-colored concrete floor depicts a young male subject, dressed in a dark t-shirt, dark shorts, and light slip-on shoes, crouched over a scientific setup. He is operating a yellow handheld X-ray fluorescence (XRF) analyzer labeled "Lab-011 XRF" which rests on a clear plastic sheet. His right index finger points towards the device or the sample beneath it. Directly below the analyzer and plastic sheet is a dark, granular material arranged in several parallel rows, each containing small, circular indentations. The lower leg and foot, clad in dark sandals and torn dark trousers, of a second individual are visible on the left side of the frame, standing adjacent to the primary subject.
