Prompt: Capture the essence of intellectual conversations in a 17th-century English coffeehouse, known as a \"penny university.\" Illustrate two individuals engaged in clear and detailed discussions over coffee, ensuring their faces are prominently featured with distinct facial expressions. Emphasize the historical accuracy of their attire and the surroundings. Utilize chiaroscuro lighting to enhance the clarity of their faces while maintaining the warm, inviting atmosphere of the coffeehouse. Opt for a 16:9 aspect ratio to encompass the scene, and employ a Leica 50mm lens for its classic touch. Set the ISO for optimal clarity, resulting in a hyper-realistic 4K resolution that vividly portrays this historical moment.
