How does Photonic Engine specifically improve texture and detail in mid-to-low light iPhone images beyond simply reducing noise?

Photonic Engine specifically improves texture and detail in mid-to-low light iPhone images beyond simply reducing noise by applying Deep Fusion at an earlier stage in the image processing pipeline, directly on uncompressed image data from the sensor. Traditional image processing pipelines often apply noise reduction and other computational photography techniques later, after some initial processing or even compression has already occurred, which can inadvertently discard fine textural information. Deep Fusion is a computational photography technique that captures multiple exposures—typically a series of standard and underexposed frames, along with a long-exposure frame—and then analyzes them pixel by pixel. When applied at this earlier stage by Photonic Engine....
