Generate a highly detailed, photorealistic image of a solitary deep-sea diver, equipped with a vintage brass diving helmet featuring a single illuminated viewport and a heavy, textured canvas suit. The diver is actively exploring the remnants of ancient underwater ruins, which include barnacle-encrusted stone columns, partially submerged archways, and moss-covered statues. The scene should be dramatically lit by focused beams of artificial light emanating from the diver's equipment, cutting through the murky, dark blue water. Around the ruins, include specific ancient artifacts such as corroded amphorae, weathered stone tablets inscribed with unknown symbols, and scattered glinting gold coins. Capture the image from a slightly low-angle perspective to emphasize the vastness of the ruins and the isolation of the diver, creating a mysterious and awe-inspiring atmosphere with strong chiaroscuro lighting.
