Prompt
Create a realistic portrait of Paul Crutzen, a middle-aged man with a gentle face, wearing a suit and tie, with a subtle background hinting at his work in atmospheric science, such as a faint image of a globe or atmospheric layers; he should be depicted in a contemplative pose, reflecting his significant contributions to the understanding of ozone depletion and the concept of the Anthropocene, for which he was awarded the Nobel Prize in Physics in 1995.
