Sight and the camera The individual parts of the eye work in a manner similar to a camera.
=
Lesson 3: History of Moving Images
The cornea
acts like the lens in a camera.
... helping to focus light to the back of the eye.
Lesson 3: History of Moving Images
The iris and pupil act
like the aperture of a camera.
Lesson 3: History of Moving Images
If you are outside at night,
the iris opens and gets bigger to let in
more light so you can see in the dark.
Lesson 3: History of Moving Images
If you are outside in the bright sun,
the iris in your eye constricts and gets
smaller to let in less light.
Lesson 3: History of Moving Images
The very back of the eye is lined with a layer
called the retina which acts very much
dddddd like the image sensor in a ddddddddddddddddddddddddddddcamera.

a camera obscura is an
optical device that projects an image of its surroundings on a screen.
Light from outside passes through the hole and strikes a surface inside where the outside scene is reproduced upside-down, but with color and perspective preserved.

a pinhole camera is a camera that
does not have a lens.
In place of a lens is a single small hole on one side. Light from outside of the camera passes through the hole and projects an upside down image on the far side of the box, across from the hole.

traditional film camera
A still camera is a type of camera used to take photographs. Traditional still cameras capture light onto photographic film.

How do images move?
• persistence of vision
• zoetropes
• beta movement
• animation through flip books
Lesson 3: History of Moving Images
what is persistence
of vision?Persistence of vision is a commonly accepted, although somewhat controversial theory, which states that the human eye always retains images for a fraction of a second (around 0.04 seconds).
Lesson 3: History of Moving Images
This means that everything we see is a subtle blend of what is happening now and what happened a fraction of a second ago.

Beta Movement is a perceptual illusion whereby two or more still images are combined by the brain into surmised motion.

What just happened?did it look like the ball moved to the right?This did not actually happen, but the cognitive process of perception links the two images in time and causality.

A zoetrope is a device that produces an illusion of motion in an image through a succession of static pictures. !The word is from the greek language with “zoe” meaning "life" and “trope” meaning "turn", translating loosely as "wheel of life".
