There was a piece on one of the news shows this AM. A guy still makes Daguerreotypes (the actual plates, from raw materials!) in New York City. Basically that stuff must be like ISO 0.05 because he was making exposures from 30 seconds to 4 minutes, achieving the 'missing people and cars' effect as a result.
Interesting, you have to admire the guy's determination. A lot of work to reproduce that technique. I have noticed that with very long exposures, anything moving very fast compared to the shutter speed just disappears, since they don't contribute enough light to the whole exposure to be distinguished from the background. I'm trying to figure out how to keep the motion blur of the subjects in daytime, which seems to require a middle ground exposure time as compared to typical exposure time of <1s or long exposures of minutes at a time.
