Johannes Kepler
(1571-1630), scholar and
|
|
|
astronomer
wrote about observing the sun
|
|
|
using a room
camera similar to the one
|
|
|
described by
Porta. Kepler described this event
|
|
in his first
published work on astronomy, “Ad
|
|
|
Vitellionem
Paralipomena” (1604). The first
|
|
|
occurrence of
the name "camera obscura" is
|
|
|
found in this
work.
|
|
|
| • |
Kepler's
portable camera obscura (tent) is
|
|
|
described in a
paper “Reliquiae Wottonianae”
|
|
|
(1651).
This is one of the earliest English
|
|
|
language
descriptions given to the camera
|
|
|
obscura.
