PERSPECTIVE DRAWING. 2nd ESO

Perspective drawing is a technique used to represent three-dimensional images on a two dimensional picture plane. When we want to draw a real object in a paper we try to represent the depth in a flat surface. This surface has only two dimensions, while the object has three dimensions. How can we do it? The answer is: using perspective.

“Perspective is to painting what the bridle is to a horse, the rudder to a ship... There are three aspects to perspective. The first has to do with how the size of objects seem to diminish according to distance; the second, the manner in which colours change the farther away they are from the eye; the third defines how objects ought to be finished less carefully the farther away they are” (Leonardo da Vinci).

Look at the image and verify Leonardo’s observations:

• Do all the objects seem to diminish according their distance to the viewer?
• Do the colours change the farther they are from the viewer’s eye?
• Do the objects less accurate the farther they are?

Picture 1

Look at  picture 2. It shows the linear perspective of the image above. Pay attention at the next points:

• All the lines join in a point called over the horizon line. This point is called vanishing point.
• Shapes appear smaller the farther they are.
• The horizon line appears at the same height that our eye-level.
  
  

  

  Picture 2

  
  

  
  

  Perspective was developed in the 15^th Century by architects. For 500 years, perspective remained one of the basic principles of Western art, until it was challenged by the ideas of the Cubists (for example Picasso) at the start of the 20^th Century.
  Knowing and understanding perspective is an essential tool to help anyone improve their drawing technique.
  
  
  There are two main elements in perspective drawing:
• Linear perspective: organizes shapes in space
• Aerial perspective: atmospheric effects on tones and colours.

We are going to practise linear perspective.

THE HORIZON AND THE EYE LEVEL

The horizon and the eye level are the axis around which a perspective drawing is constructed.

When we are outdoors, we use the horizon as a point of reference to judge the scale and distance of objects in relation to us.

In perspective drawing, the horizon has to be the viewer’s eye-level.

Look at the next pictures to explore the value of horizon and eye level.

Picture 3

In picture 3, note how all four figures share the same eye level (it’s the same than the horizon line). This suggests that they are all the same height and are standing on the same plane (on the floor). It also suggests that the figures are the same height as any viewer of the picture. As a result, the organisation of scale and distance in the drawing makes good visual sense.

Picture 4

 

In picture 4, although the figures are still the same size than in picture 1, their eye levels don’t have any relationship to the eye level of the picture. As a result, the scale of the figures is totally confused.

This demonstrates the importance of the horizon/eye level to the organisations of scale and distance in a perspective drawing. It also illustrates the meaning of Leonardo’s words “Perspective is to painting what the bridle is to the horse, the rudder to a ship”.

ONE POINT PERSPECTIVE

One point perspective uses a single vanishing point to draw an object. It is the simplest form of perspective drawing, and is the perspective we are going to work with.

Look at the next picture:

Picture 5

 

 

One point perspective has been used to draw a box.

Vanishing points are dots on the eye-level where parallel lines seem to converge and disappear. One point perspective has only one vanishing point. You can see clearly the vanishing point in picture 2.

NATURALIST DRAWING

"Nature is painting for us, day after day, pictures of infinite beauty if only we have the eyes to see them"
John Ruskin

One of the functions of visual language is describing things.  Many scientists use pictures to describe and explain nature, especially animals, plants and parts of the human body.

Drawing animals and plants as a science exercise is called "Naturalist drawing".  Those pictures are very realistic, because the author wants to show all the details of the living being he has been drawing.  The aim of the artist is that anyone who looks at the picture should be able to recognize it if they see it in real nature.  The picture is part of the author's scientific work.

We are going to practise Naturalist Drawing.  The first activity will be drawing a leaf of a tree we can find in our school's playground.  Please, pay attention to all the details and try to draw and colour it as it is exactly.

APPLIED GEOMETRY: SCRAPBOOK POLYHEDRON. 2nd ESO

We have been practising Technical Drawing for some weeks. I know that this part of the subject is difficult, and many of you find it the most boring thing in the world!

As we have drawn lots of polygons, I've thougth it could be a good idea to build 3D polygons. In geometry, they are called polyhedra (polyhedron in singular).

Polyhedra are beautiful 3D geometrical figures that have fascinated philosophers, mathematicians and artists. There are hundreds of polyhedra paper models on this site. And more here.

Our activity will be building a scrapbook icosahedron.  You will find detailed instructions here.

Material required

• Coloured cardboard
• Geometric compass
• Pencil and rubber
• Scisors
•  Ruler
• Glue

You also can follow the instructions given in the next video:



This activity is inspired in Mayalen's "Bola para regalo"

3D HANDS

                                                                           

                        With 4th grade students we draw our own 3D hands

HUNDERTWASSER: A COLOURFUL ARTIST. 3st ESO

In Art History, many artists have used colours as one of their main issues, especially Impressionists.  They thought that colours could express any emotion, and they painted using colours and all their strengh.

Hundertwasser (1928-2000) is an  Austrian artist who developed his work in different areas, such as architecture, design, clothing or painting.  He always used bright colours in his compositions, creating an special athmosphere in all his artworks.

Here you can see the Hundertwasserhaus, in Viena.  You can appreciate its sinuous shapes and bright colours, as if it was designed and painted by a child.

 

More examples:

 

Many paintings:

He also developed his own philosophy of life: he thought that life should be in harmony with nature and the individual creativity.  He named it "Five Skins Theory".

ACTIVITY

1.     In groups of two, search for some information about the Austrian artist Hundertwasser.  You should make a “prezi” containing the next information:

a.    Biography: interesting facts about his life.

b.    Oeuvre:  different areas in which he worked, characteristics of his artwork, how he used colours...

c.    Philosophy: try to explain the “5 Skins Theory”.

d.    You can add some pictures.

2.    Individually, choose one of his paintings and try to reinterpret it.  Use an A3 cardboard.  Draw it using pencil, and colour it with paintings.

PAINTING AS POLLOCK

JACKSON POLLOCK (1912-1956)

He was an expressionist, abstract american artist.

He was known for his ACTION PAINTING

He didn't paint using brush strokes, but he poured and

splattered paint on big canvas which he laied on the floor.

We painted as Pollock with students in 3r, and it was great fun. 

COLOUR THEORY. 3rd ESO

Christmas Ornaments. 5è primària

To make this Christmas tree ornament, the students started by cutting 20 colored circles of 6 cm diameter. Then they cut different patterned triangles and some pictures of their families and they glued them to each circle.

The next step was to fold each circle into a triangle, creating three sides. Then, they glued the side of one with the side of another in groupings of five, making 2 “hats”.

Afterwards, they added 10 circles in one “hat” by gluing the folding edges together. Next, they glued the other “hat” to the other side.

The final step was to thread a ribbon through a hole at the top of the ornament.

Now, it’s ready to be hung in your tree!

Patterns and dots. Snakes. 5è de primària

The students painted a snake using cotton buds. Firstly, they painted a large black snake curling around a paper, previously painted with rust paint. Then, they printed lines of ochre and brown dots on the snake. The last part consisted of adding white dots around the outline of the snake and printing black and white flowers on the background.

TRENDY MONA LISA. 1st ESO

Leonardo Da Vinci painted the Mona Lisa in 1503.  The tecnique is oil on poplar, and the dimensions are 77cmx53cm.  The style of the painting is sfumato, without outlines or borders.

You can see the painting at the Louvre Museum, in Paris.

What do you thing about her?

• What does she look like?
• What is she wearing?
• What can you see in the background?
• Where is she looking to?
• Which colours has the artist been using?
• What do you think she is thinking about?
• How old could she be?

Now it's your chance to draw and paint your own Mona Lisa.  Try to represent a 21st Century Woman, original and up-to-dated.

Material required:

• A3 cardboard
• Pencil, eraser
• Coloured pencils or felt-tipped-pens

PORTRAITS. 5è primària

The students of 5è drew a portrait of one of their classmates.

They had to be very concentrated to make the portrait as close as possible to reality. They worked in pairs. The model had to be calm and relaxed because his partner had to observe every detail of the face very carefully. When they finished, the model turned into a painter and vice versa.

The results were very satisfactory. Do you like them?

CHIAROSCURO PORTRAITS. 3rd ESO

After some weeks practising the Chiaroscuro Technique with geometric figures and still lives, it's time to try  using it in faces and portraits.
One of the main issues in portrait drawing is how to mantain proportions. Here you have an excellent website called "How to draw a head".  It will be our guide to get our goal.

Activity:

Choose a celebrity you would like to draw.  Find a black and white picture of his or her head and try to draw it following the instructions you've seen in the website.  After drawing, colour it using the Chiaroscuro Technique.

Good luck!

LANDSCAPE USING LINES. 2nd ESO

We started working "Basic elements of visual language" drawing and painting with dots.  Now it's time to use lines as main elements in a composition.

In this link you'll find the powerpoint we've been working with.

ACTIVITY: LANDSCAPE USING LINES

Draw and colour a landscape using different kinds of lines (wavy, straight, horizontal, curved...).  Try to give the composition a sensation of depht, tracing thicker or thinner lines depending on their distance.  If the part of the landscape that you want to represent is closer, use a thicker line than if it's farther.

Material required:

•  Coloured pencils and felt-tipped pens
• Set square, ruler.
• DIN A4 cardboard with 2cm frame.

You can get inspired by these compositions made by other students (taken from the blog plasticaeso)

CREATING OPTICAL ILLUSIONS - RESULTANT PICTURES. 1st ESO

Finally I've been able to upload the pictures that 1st ESO students took to creat optical illusions. Here they are:

SCARY BATS

We made these scary bats for Halloween. It was just a cutting and sticking activity, but the result
was amazing.

GRAFFITIS

We have been studying graffitis. We went around Torelló looking for graffitis and observing them. Then we listed out all the characteristics they have in common. Finally, every student drew  its own graffiti.We enjoyed it a lot.

Here you are, the graffitis and graffiters pictures.

BASIC ELEMENTS OF VISUAL LANGUAGE: DOT. POINTILLISM. 1st ESO

Some really gorgeous examples about painting in pointillistic style. Painted by 1st ESO students from a school in Pontevedra:

CREATING A VOKI

A Voki is an animated icon.  It moves itself and speeches, reading a text you have introduced before.  We can use a Voki as a personal image, adding it to our blog or webpage.

First step to create a Voki is going to the webpage http://www.voki.com.  You need to sign up (register).  Next, go to "Create" and you'll be able to start. Many of the images are free, but some of them must be paid (they wear a hat).

There is a tutorial which explains how to do it step by step (in Catalan):

https://sites.google.com/a/xtec.cat/ajudaxtecblocs/insercio-de-continguts/animacio-voki

You also can watch this video (in English), that explains clearly the process:

Activity

Create your own Voki.  Please, choose a free human character (not a pet or anything else).  Your Voki should represent yourself ( how you look like now or you want to be in the future).  The background can contain your hobbies or favourite places.  Give it a voice in English using your tab.  Please, be polite.

Send the result to the teacher's e-mail.

Enjoy it!
