Night Sight for Pixel phones
I would like super sensitive cameras like this to be used inside fridges to see the very faint glow of food going off.Chemical reactions by bacteria breaking down food produce light, enough for humans to see in only the darkest of places (if you live in a city, you won't ever encounter dark enough situations).A camera simulating a 1 hour exposure time in a closed refrigerator ought to be able to see it pretty easily.
