A man is walking through a dark, narrow underground passage. The camera is set with a wide aperture at a low f-stop value (e.g., f/2.8) to create a shallow depth of field, isolating him from the background. A professional DSLR camera, such as the Canon EOS 5D Mark IV, is used.

The composition of the scene highlights the contrast between the man and the gloomy underground surroundings, emphasizing his presence in this enigmatic place
