Sound of a "Flashing powder" flash.
In the middle of the 19th century, the average exposure time in photography was around 30 seconds. In 1887, Adolf Mieetke and Johannes Gaedicke invented "Flashing Powder". It is an explosive mixture made of magnesium, potassium chlorate and antimony. Once ignited, its combustion provides a bright light, noise but also a lot of smoke. The first flash was born and made it possible to shorten exposure times.

Old rotary telephone. Pick up, then dial my own cell phone number. It is possible to compare the duration to find my number. Text me if you find out. Don't forget to add the France code if applicable. Duration: 00:24.
