Arie van't Riet is a Dutch physicist who creates imaginatively composed X-ray photographs. He first began taking X-ray photographs as a means to demonstrate how the machine worked to his scientific students and colleagues. But by adding colour and carefully composing his work, van't Riet realised there was great demand for prints of his works at exhibitions and galleries. He says: 'Nature is amazing under X-rays - it really shows the complexity of the animals and plants. My principal objective is now to use X-rays to show the beautifulness of nature.'
