1.- Concept of Shape


                      2.- How can it be seen?
                          Contour, interior
                    contour/surface, silhouette .

                        3.- Sorts of Shapes:
                   closed/open; regular/irregular;
                     symmetrical/asymmetrical.
BASICS OF VISUAL
  PERCEPTION          4.- Relations between
                     shapes: resizing, contact,
                     separation, trnasparency,
                       overlap, intersection.



                   5.- Shape and Space: Depth
                      indicators: disposition,
                     resizing overlap, contrast,
                         sharpness, texture.
• Everything
around us is
shaped.
Matter can
not exist
without shape
or form.        Sonia Delaunay
FORM AND SHAPE
A triangle, which is two
dimensional, is a shape, but
a pyramid, which is three-
dimensional, is a form.
•Definition:
An enclosed
area defined
and
determined by
other art
elements
(colour,
textures, etc.);
2-dimensional.
By its contour:               By its interior
Lines that surround           contour/surface: lines,
and define the edges of
a subject, giving it shape.   colours and
                               textures
                              that
                              form the
                              surface
                               of a shape.


By its silhouette:
representation of the shapes
through a single colour or tone.
A) Closed
Shape:
Space that is
completely
enclosed by
a line, or
unbroken
contour.
                Paul Klee
B) Open
Shape:
space that is
not
completely
enclosed by
a line.
                Turner
•A) Regular:
both sides and
angles equal ;
also the
circumference.

•B) Irregular:
all others.
•A) Positive:
shape is
perceived as
part of a space.
•B) Negative:
shape is
perceived as a     POSITIVE   NEGATIVE
void.
•A) Symmetrical: a    Symmetrical   Asymmetrical

shape that has two
identical halves in
both shape and size
divided by one o
more axes.
•B) Asymmetrical:
the absence of
symmetry.
•1. Resizing: to create
the illusion of distance
and closeness we can
vary the size of the
shapes, placing the
largest on the bottom
and the smallest on
top.
•2. Contact: if we
place two objects in
contact we are
placing them at the
same distance from
the observer.
•3. Separation: the
shapes can be
separated
diagonally to
transmit a sense of
depth and more
space between
them.
•4. Transparency:
shapes that are
situated beneath a
transparent one,
give the sensation
of being behind it, a
little further.
•5. Overlap:
to obtain the
sensation that a
shape is behind
another, we will
hide a part of it.
•6. Intersection:
it occurs when two
shapes intersect
creating a new
one.
• The resources used to
suggest depth in an image are
based on our perception of
size:
  • Two identical shapes
  located in the same
  horizontal line do not
  produce any feeling of depth.
• LAYOUT
The sense of
distance is
accentuated when
the shapes are
located on different
horizontal lines
and the smaller one
above.
• RESIZING
Experience shows
that a distant object
it seems to be
smaller, so, between
two shapes, the
smaller will seem
the farthest.
• OVERLAP
Due to experience
we know that if
two objects are in
the same line of
sight, the closest
hide the other.
• CONTRAST
The use of different
colours and light
also gives us a sense
of space.
• SHARPNESS AND
TEXTURES
The sharpness and
detail of the textures
indicate that shapes are
on the foreground,
while the blurred
contours suggest that
they are on the
background.

  • 2. 1.- Concept of Shape 2.- How can it be seen? Contour, interior contour/surface, silhouette . 3.- Sorts of Shapes: closed/open; regular/irregular; symmetrical/asymmetrical.
