Earlier this fall, amazing photographer-slash-science-geek Caleb Charland emailed me some samples of untouched images from a recent shoot he had completed. One of them was a tremendous photograph of a peeled and sliced orange turned into a generator for a small LED light. After a 14-hour exposure, the light’s glow recorded on film, Caleb found himself the creator of a gorgeous work of art that illustrates a wonderful bit of science as well. This type of photograph—Caleb’s specialty—struck an obvious chord, and now the image has essentially gone viral, popping up on photo and science blogs all over the world. (If you haven’t seen it, check out the link below to find the photo at Boing Boing, including a bit of text about the photo direct from Caleb himself.) Since it’s garnered such attention, Caleb is now offering it for sale in a limited edition of fairly affordable prints from Lux Archive. If you’re as much of a fan of his work as I am, this one’s a no-brainer.
