The pinhole camera is a simple camera without a lens that uses a small aperture to project an inverted image. The Persian scientist Alhazen first wrote about and studied naturally occurring pinhole cameras in the 11th century. He discovered that a smaller pinhole creates a sharper image. In 1827, Joseph Nicephore Niepce created the first photograph using a camera obscura, demonstrating the photographic capabilities of the simple pinhole camera design.
2. What is the pinhole camera?
It is a simple camera without a lens and with a
single small aperture
Light proof box with a small hole in one side
Light from a scene passes through a single point
and projects an inverted image on the opposite
side of the box
3. The Invention
Alhazen (Persian Scientist) wrote about naturally
occurring pinhole cameras like wicker basket slits
or crossing tree leaves
Pinhole images of the sun make the camera
possible
Alhazen figured out that the smaller the pinhole
the sharper the image
4. Ways to use
You can use a closed container with a hole in it so
that light passes through to create an image
Tree leaves have shapes in between them and the
light comes through making a perfect projection of
the sun
5. Time Periods
The 4th century was the beginning of the pinhole
camera and Aristotle was the one who mentioned it
The entire technique was brought about in the
thirteenth and fourteenth century
6. The First Photograph
In 1827 Joseph Nicephore Niepce made the first ever
photographic image with the aid of a camera obscura
Prior to this, the people used the obscura to draw or
view things
