Large Format Slide Projector
Encyclopedia
A large-format slide projector (also often called "large-format projector" or "large-image projector") is a kind of slide projector
which has a very powerful light source (up to 12 thousand watts using arc lamps). Therefore it is necessary to use a large slide format to protect the slide material from overheating during the projection process (even when the light is filtered to only visible light and the slide is cooled with strong slide cooling fans). Slide formats of 18 × 18 cm (7.1 × 7.1") or 24 × 24 cm (9.4 × 9.4").
On the other hand this formats are so large that it is possible to project slides painted with heat resistant translucent colours as a special kind of art (projection art). The light output of the projector is so enormous that it is possible to cover whole buildings with an artistic cover of light. More and more it is growing to a slow but nevertheless impressive high power alternative to the fast running video projections. So you may say the large format slide projector is a tool for a specialized group of artists which produce monumental light artwork. Current specialists which are working with this type of projectors are listed below.
used the large format slide projectors as stage projectors in their artwork. In good cooperation with the technician Ing. Ludwig Pani they realized the first large format projections as an integrated part of their artwork. Since this starting era the large format slide projectors were developed to more light efficiency and flexibility to reach all fields of large image projection as there are stage, event, architectural and advertising projection.

A slide projector is an opto-mechanical device to view photographic slides. Slide projectors were common in the 1950s to the 1970s as a form of entertainment; family members and friends would gather to view slide shows...

History
The first large-format slide projectors were built in the middle of the 20th century as background projectors for theaters and opera houses. The artists Prof. Schneider-Siemmsen, Prof. Svoboda and Herbert von KarajanHerbert von Karajan
Herbert von Karajan was an Austrian orchestra and opera conductor. To the wider world he was perhaps most famously associated with the Berlin Philharmonic, of which he was principal conductor for 35 years...
