Light does not travel in a single direction; it explores all possible paths, and the paths observed are those where these individual paths interfere constructively.

“But now I will prove to you that light doesn't set out in only one direction. Instead, it really does explore all possible paths.”

Individual photons do not contain image information, which is only reconstructed through an ensemble of photons interacting with a lens.

“So you're right. A photon alone contains no image information. You need the ensemble of photons to do so.”
