Definition

• But… What is an optical illusion? What do you understand by this term?

• What is it? This is a bottle of wine pouring into a glass of wine. The wine seems to be falling into a woman’s mouth.

• Do you think this is easy to take?

It is a photograph or a drawing made with the idea of surprising the viewer, making it appear two different things or placing together two things which you don’t expect. They are images that don’t appear to be what they really are.

What is there in this picture?Who is there?Where is it? Why is there a statue of him there?

• Statues offer a good opportunity to take this kind of pictures.

• Do you think this picture is easy to take?• How do they work?• Basically, it’s our minds trying to find the easiest way

to look at things. • At a first glance, we try to relate the image with the

most basic and close interpretation of it, and only after a few seconds do we realize that separate details of the image don’t even make sense.

Which one of these faces is female, and which is male?

They’re actually the same androgynous face, just with different levels of contrast, which makes one appear male and one female.

PLAYING AND DRAWING PHOTOGRAPHS:- Choose one person in your group who draws well. - This person turns back so he/she cannot see the presentation in front of the class. - Take the stapled set of blank paper and write your group number and group components.- In each sheet of paper write the number of the picture and agree on a catchy title for the photograph.- Draw a picture of the photo as your group is describing to you.

• The rest of components sees the photo in the presentation and describe the photo both in English and Spanish.

• You will be scored a negative point each time we check somebody is cheating looking at another student’s drawings or getting help from somebody who is not in your group.

• You need to stop drawing this picture as soon as the teacher goes to another photograph.

• You can change the person in charge of drawing in your group when a different photograph is shown.
