Leonardo
(1452-1519), familiar with the work of Alhazen and
|
|
|
after an
extensive study of optics and human vision publishes
|
|
|
the first
detailed description of the camera obscura in “Codex
|
|
|
Atlanticus”
(1502):
|
|
|
“In the facade of a building, or a place,
or a landscape is
|
|
|
illuminated by
the sun and a small hole is drilled in the wall of
|
|
|
a room in a
building facing this, which is not directly lighted
|
|
|
by the sun,
then all objects illuminated by the sun will send
|
|
|
their images
through this aperture and will appear, upside
|
|
|
down, on the
wall facing the hole”
|
|
|
"You can catch these pictures on a
piece of white paper, which
|
|
is placed
vertically in the room not far from that opening. The
|
|
|
paper should
be very thin and must be viewed from the back.”

Leonardo calls
the camera obscura the “oculus artificialis” -
|
|
|
“the artificial eye”
