Blank Roll

Can image represents the truth or preserves the reality?  In 2023, during my travel in Mexico, I had a serendipitous encounter with a 6-year-old boy at an archaeological site. We went into the jungle for adventures, where he guided me to the undeveloped area of underground Mayan tunnels, temple, showing me the endemic animals and plants. I took pictures of him with my film camera, but the rolls were completely blank after develop.
