In the 19th and early 20th century indoor and night photography required flash for a decent exposure. Unfortunately, the magnesium powder that created a bright light when ignited was unstable and unless great care was taken, it would suddenly explode creating both a flash and a loud bang frightening and potentially injuring both subject and photographer alike.<\/p>\n<p>In the 1920s, \u00a0a clever German design used a new process to convert the magnesium powder to a ribbon and housed the unused reel of magnesium in a fire-proof box. Only enough ribbon was exposed to give a suitable amount of light. Eventually, the magnesium was contained in a glass bulb and ignited by a small battery when ever a brief burst of light was needed.<\/p>\n<p>This drawing and article was discovered by George Dunbar in the February 1926 edition of the magazine <em>Science and Invention<\/em> during his research into photographic history.
