The oldest lantern slides I have been able
to find were huge -- 8x10s! Like all lantern slides, the image was sandwiched
inbetween two fairly substantial pieces of glass. They were used basically the
same way as our current slides, as a way to project visual information for a
group. Lantern slides held a remarkable amount of visual detail for their time,
but lacked color and were NOT particularly easy to use. Lantern slide projectors
were made of cast iron and wer typically over a yard in length. When you look at
the projectors in the images below, remember that the slides are an eighth of an
inch thick and about 3x4 inches! These factors, and their fragility, all
contributed to their ultimate failure as an educational technology, although
they seemed to endure in use for astronomers longer than they did in the health
sciences. Nowadays, you tend to find them in creative art projects and antique
stores more often than the use for which they were intended.
