In some slapstick comedies, a cloud of smoke might then dissipate showing the photographer standing with a blackened face.

When the mixture is ignited, it burns extremely quickly producing a bright flash that can be captured on film. Before being used for photography, flash powder was commonly used in theatrical productions and within fireworks — a practice we continue to this very day.</blockquote>
