What Are Optical Illusions?

OPTICAL ILLUSIONS:

• An image that you percieve that differs from reality
• They are also known as "normal" illusions
• Anyone with a normal eyesight would experience them

Why do they happen!?
They occur when your brain makes the wrong conclusion about what your eyes are actually seeing

LETS GET MORE INTO DETAIL!

Each eye has a blind spot because there are no light receptors where the optic nerve leads to the brain. Both your eyes and your brain work together to enable you to see things. Info: the image is received by your eyes, then passed to your brain where many processes of classification take place. The way people's brains interprets this is called perception. Let's show you a diagram of an eye!

HAVE YOU EVER HEARD OF A MIRAGE?

This is a mirage. Mirages are images of objects that are not what they seem to be. It is a type of optical illusion. They may include far objects that seem closer than they really are, or they may seem to float in the sky like mountains.

A mirage may appear while a person is driving. The driver may sight a puddle or pool of water lying on a hot, paved road up ahead. Though when he or she reaches the "puddle", it has disappeared. Mirages can include distant objects that seem to be closer than they really are.

Let's give you an example of a simple optical illusion! A white house may look larger than a black house of the same size.

Another example is one which you may see every day!
A person wearing a shirt with stripes going up and down, looks thinner than someone wearing stripes that go from side to side.

Read the following: The man walked though the busy street.

Your brain probably expected to see the word "through" so you did. The actual word was though. This is not an optical illusion just a mistake with what you want to see. Feel free to look back at the last slide and re-read the sentence.

From a series of still photographers on film, motion pictures creates the illusion of moving images!!!!

HOW FILM MAKERS DO IT

Film makers use the same tools and technology to produce most types of movies, from full length features, to short films/documentaries.

EXAMPLES OF SUCCESSFUL FILMS

• Star Wars Series
• Star Trek
• The Hulk
• Spiderman
• Iron Man (and any Marvel film)

WE ARE FINALY DONE!

NOW FOR A SUMMARY!

First, we learned that optical illusions are things we see that differ from reality. Then we learned the connection between optical illusions, your brain, and your eyes. Next we told you that mirages are images of objects that are not what they seem. Then we showed you examples of how mirages, optical illusions, and mind fooling tricks work in real life. Finally we took you behind the scenes in movie making. We hope you enjoyed this presentation.
