Coloured X-ray of a barn owl. A physicist has used X-ray to create an extraordinary collection of artwork. Arie van't Riets pictures reveal birds, fish, monkeys and flowers in an incredible new light. The 66-year-old, from Bathmen in the Netherlands, began X-raying flowers as a means to teach radiographers and physicians how the machine worked. But after adding a bit of colour to the pictures, the retired medical physicist realised the potential for an exciting new collection of art. (Photo by Arie van't Riet/Barcroft Media)

Australian photographer Brendan Fitzpatrick’s X-ray photographs expose the inner workings of toys. Fitzpatrick’s photographs are both whimsical and mechanical, evoking the curiosity of childhood and the desire to discover how things look and work from other perspectives. The strategic placement of wires, batteries, and screws are revealed, the complexity of the inside contrasting with the seemingly simplistic design of the outside. Fitzpatrick uses chest X-ray and mammogram machines to photograph flowers, toys, and creatures, then enhances the color in the images in order to more effectively distinguish the various parts that have been exposed. This photographs are part of series he calls “Invisible Light”. (Photo by Brendan Fitzpatrick)
