Dissolving Views

This lantern is called a "biunial" (two in one) it was a precision instrument used to create startling special effects on the screen. With such an apparatus one slide could be made to dissolve into another creating startling effects (e.g. day becoming night etc). Even more complex results could be achieved with a "triunial" ( three in one lantern)

Dissolving  views  could be  used  to  make  one  picture subtly  change  into  another or superimpose  one  image  on top of another  to add drama  to  a show (for  example  the appearance of  angels )
