"When shooting a photo in low light, a low-ISO long-exposure photo requires a stable camera and blurs movement in the frame while a high-ISO short-exposure photo can be plagued with noise and poor quality. Now AI is bridging the cap, opening the door to low-ISO image quality while shooting at faster shutter speeds.
A group of researchers at the University of Illinois Urbana-Champaign and Intel have published a new paper titled Learning to See in the Dark. It explains how they trained an AI to do low-light image processing and produce results that are much cleaner and more usable than traditional high-ISO photos.
The team put together a set of photo pairs, with each pair containing a RAW short-exposure photo and a long-exposure version."

"You can find more comparison examples on the research project’s website and read the paper if you’d like to learn the technical details behind the experiment.
Experiments demonstrate promising results, with successful noise suppression and correct color transformation,” the researchers write, but they note that this is just the tip of the iceberg. The experiment lays the groundwork for much more exploration, including things like having the AI have what could be considered “Auto ISO” instead of having to provide the amplification ratio for each photo."
