Prompt
Create a realistic portrait of Sir Norman Lockyer, a British astronomer and scientist, in a study setting surrounded by books and papers, with a warm and introspective lighting. He should be depicted wearing formal attire, including a suit and tie, with a slight smile on his face, conveying a sense of wisdom and accomplishment. In the background, a subtle hint of a solar spectrum or a astronomical chart should be visible, paying homage to his groundbreaking work in the field of astronomy and the discovery of helium. The style should be reminiscent of a Victorian-era photograph, with a muted color palette and a sense of nostalgia.
