History
Since the 1800s, flash has been used to replicate authentic light in photographs. Photographers used magnesium flash ribbon to create a reaction of light. Flashbulbs then became the industry standard leading into the early 1900s of photography. Instead of an open flame, the magnesium reaction was contained in a glass dome, connected to the camera. These flashbulbs were not reusable with the magnesium reaction because it was not until the 1950s when electrical flash was introduced to camera consumers.
The electrical flash took a few adaptations for it to become practical and affordable for the market. Electrical flash units can be mounted on cameras and are usually built into most consumer cameras today.
