EVALUTION.

Name of inventer: Emilie Reynaud.
INVENTION: praxinoscope
Date of invention: 1877.

Why is your invention so important?

-The Praxinoscope was a rather important part in history as it was the first device to overcome the picture distortion. I also think The Praxinoscope was important as it was the very begining of
 animation and cartoons, the start of a new era. But the disadvantages of the Praxinoscope is that only one person can view it at a time.

                                                          
 Name/describe some cartoons they made.

 What is your personal repsonse to this invention?

- I enjoy learning about the praxinoscope. The reason why i liked it was that it didn't require any technology it was all hand made, it was pretty simple and an imaginative creation.

What is persistance of vision?

persistence of vision is a visual phenomenon where an image is retained in the eye for a short period of time, creating an illusion of continuous motion in film and video.

Whats the difference?

Whats the difference betweena Zoetrope and a Praxinoscope?

- They both do the same thing, they make pictures move and you spin them.
 The Praxinoscope has strips of pictures and they blur into one which makes it looks like its moving. But Zoetropes have slits, to look through and Praxinoscope have mirrors to look at.

Whats the difference between a theatre optique and a praxinoscope?

- A theatre Optique is projected on film whilst rotating and is much bigger. The Praxinoscope is a tiny band of pictures that only rotates and does not have any film.

PRAXINOSCOPE.

PRAXINOSCOPE.

The praxinoscope, invented in 1877 by the Frenchman Charles Reynaud, was the first device to overcome the picture distortion caused by viewing through moving slots.  
a band of pictures is placed inside a shallow outer cylinder, so that each picture is reflected by the inner set of mirrors.  The number of mirrors is equal to the number of pictures, and the images of the pictures are viewed in the mirrors.  When the outer cylinder rotates, the quick succession of reflected pictures gives the illusion of a moving picture.

KINEMATOSCOPE.

The Kinematoscope was invented in 1861 and created by Coleman Sellers.

- A series of still stereographic images with chronologically successive stages of action were mounted on blades of a spinning paddle and viewed through slits. The slits passed under a stereoscopic viewer. The pictures were visible within a cabinet, and were not projected onto a screen.

The Zoetrope.

The Zoetrope was invented in 1834 in England by William Horner. The zoetrope worked on the same principles as the phenakistiscope, but the pictures were drawn on a strip which could be set around the bottom third of a metal drum, with the slits now cut in the upper section of the drum. The drum was mounted on a spindle so that it could be spun, and viewers looking through the slits would see the cartoon strip form a moving image. The faster the drum is spun, the smoother the image that is produced.
