I don't know how interesting this will be to anyone else, but I love looking at photos that were taken of businesses at night time in the 1930s and 1940s. These used to be very common in the days when film stocks were not very good at low light, so commercial photographers would go out at 3 or 4 in the morning when there was little to no traffic going past, open up the shutter all the way, and take a good long exposure. My dad did these kinds of photos back in the day.
The photos look kind of cool and unearthly, with no human presence and really dark darks and really bright lights. They look like something out of an Edward Hopper painting or a film noir movie.
These were in Phoenix, Arizona.
