A man wearing jeans and a gray T-shirt is positioned in a dimly lit, confined underground chamber. The camera is set to a wide aperture, with a low f-stop number (e.g., f/2.8) to create a shallow depth of field, isolating the subject from the background. The camera model is a high-end DSLR, such as a Canon EOS 5D Mark IV. To capture the scene's eerie ambiance, the shutter speed is set to a slower value, around 1/30th of a second, allowing for a subtle motion blur and emphasizing the atmospheric lighting. The composition should highlight the contrast between the man and the dungeon's gloomy environment, drawing attention to his presence in this mysterious setting
