Fog image
Fog images , also known as Dissolving Views , or Dissolving Pictures , were projected images that gradually merged into one another.
In the 19th century they were mostly painted, later they were photographs that were colored. The carrier medium was glass. To obtain a fog image, two fog imaging devices, for example two magic lanterns , were placed next to each other in front of a projection surface. The lens tube of one of these devices was closed so that only the image of the other device was projected onto the screen. A simple mechanism was used to uncover the lens of the currently closed device, while the lens of the second device gradually closed. The image projected on the wall slowly disappeared, and the new image emerged just as slowly. This gave the appearance that one image was transformed into the other.
For example, you could visualize the smooth transition of the seasons like in a film. The same could be done with writing, with play of colors and ornaments. For lighting was often limelight used later they used more electric light. The fog pictures were the forerunners of the first cinema programs, as movement came into the picture for the first time.
