MAGIC LANTERN
Lantern Slides
Magic lanterns used glass slides
with images which were
projected.
Early Presentations
Magic lanterns and other
devices had been
employed in popular
entertainment for
generations.
Early Cameras
• Based on the Camera
Obscura
• In 1822, Joseph Niepce
made a permanent
image on exposing
coated pewter plates.
• In 1851, wet-plate
photography required
traveling with
cumbersome portable
darkrooms
Limelight Oxygen-Hydrogen Burner,
used in lantern projectors
With the advent of limelight, the intensity of the light source
made it possible to project bigger images to a larger audience.
Eadward Muybridge
Most famous experiment involved the
photographing of racehorses to prove
that at a point in their gallop all four legs
are in the air
Thomas Edison
"I am experimenting upon an
instrument which does for the eye
what the phonograph does for the
ear, which is the recording and
reproduction of things in motion ...."
--Thomas A. Edison, 1888

Invention of Radio
• In 1895, the wireless radio
was developed by Guglielmo
Marconi.
• Broadcasting officially began
in the US in 1910 when Dr.
Lee DeForest, the "father of
radio broadcasting,"
transmitted a five opera from
the Metropolitan Opera
House in NYC.
Early Television
• In 1923, Vladmir Zworykin
developed the iconoscope, - the
TV camera tube. It aimed a beam
of electrons across a target that
had been charged by light
imprinting on it.
• He also developed the kinescope-the TV picture tube. It gave off a
phosphorous glow with the
electron stream.
Video Storage
• In 1951 Bing Crosby laboratories
introduced the VTR, which recorded
the electrical impulses onto magnetic
tape.
• In 1963, D. Gregg, an inventor at
Stanford University, created a
crude forerunner to digital
photography. The videodisk
camera could photograph and store
images for several minutes.
Early Digital Images
• In the 1960's, NASA sent probes to
map the surface of the moon. The
analogue signals were too weak to
compete with natural radio sources
in space.
• The images were processed through
a computer and turned into a digital
signal, and all noise and corruption
of the data was removed.
CD and DVD Disks
• In 1979, videodisk made digital imagery a practical
reality. Using computer technology, sound and
images were digitally recorded and then imprinted
as micro-pits on a disk. A laser then optically
scanned the information, and converted it into
pictures and sound on a home TV.
• In the 1980s, the compact disc (CD) Audio
technology allowed the reemerged of digital
photography with video disk.
Digital Photography
• In the mid 1970s, Kodak and other companies began
investigating filmless technologies that could capture
images with solid state circuitry.
• In 1986, Kodak succeeded in creating a sensor that
could record 1.4 million picture elements, or
megapixels.
• In the 1990s the first digital cameras appeared for
commercial use.
The 21th Century
‘Magic Lantern’ Show
Presentation technology is a powerful medium that
continues to evolve and change. Photograph, sound
and video, linked to computers, bounced from
satellites, and projected world wide has itself become a
visual medium for the magic lantern show.
