Lantern slides, also known as magic lantern slides, were first produced in the 1650s and used by educators, lecturers and entertainment providers. Images were hand–painted onto glass slides which were illuminated and projected with a magic lantern using a convex lens. Presenters often added elements to the slides in order to make them appear to have movement, adding to the entertainment and educational value. Using the pre-electricity lanterns proved to be hazardous, however, as they were fueled by burning candles, kerosene or gas.

History of format
Philadelphia brothers William and Frederick Langenheim introduced photographic lantern slides in the mid-1800s, a few years after the invention of photography by Joseph Nicéphore Niépce in France.

Using a 3.25–inch light-sensitive glass square and the wet collodion or the dry gelatine process, negatives were exposed under light. The resulting positive black and white images were often hand-coloured using transparent oils and watercolours. Once the image was set, a second glass slide was placed on top of the image and the two pieces were taped together.
How the format was used
Lantern slide manufacturers quickly began producing boxed sets of themed images to be used by teachers, travellers, clubs, and anyone else that wanted to organize presentations to various audiences. The invention of electricity in the late 1800s made projecting the lantern slides with light bulbs much easier and safer. As new photographic films started to emerge in the early to mid-1900s, first by Agfa and then Kodak, lantern slides were eventually phased out, giving way to 35mm colour slides.
