I know that for the very earliest daguerrotypes could had an exposure time of 5 minutes -- a very long time!  But that time was reduced as the process improved.  Depending on lighting and conditions, exposure times could be a short as several seconds.

By the way, those early photographic processes were called daguerrotypes after the inventor, <span>Louis-Jacques-Mandé Daguerre, who introduced his form of photography in 1839.  By 1860, other types of processes had also been invented and became more common in usage.</span>

Why did Americans fear communism in the 1920s?
Serggg [28]

Answer:

They believed that communism was too totalitarian and wouldn't let people choose government. 2) The U.S. is a capitalist country, and so its prosperity depends on having people buy its products all over the world. In communist countries, there is no private property, so it cuts people off from buying products.
