How a Playboy Playmate Helped Make the Internet Beautiful

Contrary to what you might think, this photo was not snapped over the weekend using Instagram's Valencia filter. It's known as Lenna and as Motherboard points out, it's one of the oldest, most widely used test picture used for all kinds of image processing algorithms.


The real name of the subject is Lena Soderberg, and the picture was actually cropped from the November 1972 Playboy centerfold. The name was later anglicized to Lenna. It was picked because late one an assistant professor at USC's Signal and Image Processing Institute (SIPI) needed something not totally boring to scan for a colleague's conference paper. Everything else was old and dull (read: lacked pretty ladies, lacked breasts) and so thank god for Playboy. IEEE told the story back in a newsletter in 2001:

They wanted something glossy to ensure good output dynamic range, and they wanted a human face. Just then, somebody happened to walk in with a recent issue of Playboy. The engineers tore away the top third of the centerfold so they could wrap it around the drum of their Muirhead wirephoto scanner, which they had outfitted with analog-to-digital converters (one each for the red, green, and blue channels) and a Hewlett Packard 2100 minicomputer. The Muirhead had a fixed resolution of 100 lines per inch and the engineers wanted a 512×512 image, so they limited the scan to the top 5.12 inches of the picture, effectively cropping it at the subject's shoulders.

So there you have it. The picture is not just memorable because it's of a foxy—probably naked but you can't tell because it's cropped—lady. It's also an important piece of digital history. [IEEE via Vice]


For decades Kodak would test their new films by shooting what they called a China lady. The lady was not Chinese she was picked because her skin was like fine china, as in porcelain. If you ever see a woman in close up looking directly at the camera with a color card in the frame, that's a china lady. So, pretty lady face seems like tradition when testing visual things.
