LAYERS IN PAINTING |
A
Achromatic - Black, white and
greys. Artwork that is executed without color.
Acrylic - Thicker and stronger than tempera or watercolor
paint, Acrylic is a water-based "plastic" paint.
Albumen Print - This printing process is used in photography
printing processes. Egg whites are used in the emulsion.
Alternative Process - This photography term covers approximately 35
different processes for the final unconventional effect.
Art Boards - Art
boards are smooth, reflective surface refracts light differently than canvas; making
colors more brilliant and vibrant. The firm, consistent surface is perfect for smooth
blending of colors, fine brushwork and minute detail. The choice of painting surfaces can
have a profound effect on the success of artwork, creating as much impact as paint or
technique. Most cracked paint seen in completed paintings results from some type of
movement in the support. Art board panels protect artwork from damage, which is caused by
the flexing and cracking of paint films. And the solid structure prevents the surface from
being accidentally dented, torn or damaged by mishandling. Wood panels are more permanent
than flexible fabric. Properly prepared art boards will have a longer life than stretched
canvas or other thin flexible supports. Witherspoon originals are made to securely mount
flush to the wall. The panels easily hang on a single nail or screw - no need for frames
or picture wire. The rigid surface of an art boards ideal for all painting mediums,
including collage, mounting prints and works on paper.
Artists Proof - A small group of outstanding prints for the artists use which
have been set aside from the edition prints.

B
Balance - An
art and design principle concerned with the arrangement
of one or more elements in a work of art so that they appear symmetrical (even) or
asymmetrical (uneven) in design and proportion.
Basic color principles - All color theory is based on the principle that
'color is light'.
An object that we see as red contains pigmentation which absorbs all of the colored rays
of white light except the red color, which it reflects. White pigment absorbs none of the
colored rays, and black absorbs all of the colors of the spectrum.
Black - The
complete absence of light. Because of impurities, you can not create black with pigments.
In most black pigments, the is a slight blue trace. A black surface absorbs all light.
Brayer - In
printmaking, a Brayer is a roller which is used to apply ink to printing surfaces.
Brushes - Brush
styles are designated by a letter following a series number. Some basic brushes to meet
your needs:
§ F- Flats, square edge, long bristle
§ B- Brights, flat, square-edged, long sable
§ R - Rounds, pointed bristle
§ L- Longs, flat, square-edge, long sable
§ Filberts- Flat, oval edge, long fibre
C
Canvas - Fabrics that are prepared for painting.
Available in panels, stretched on frames, or obtained by the yard.
Chop - An
impression made by the artist, or by the printer seal.
Chroma - This is
the intensity, or strength, or purity of a color. Squeezing paint directly from the tube
to the palette is 'full chroma'.
Cibachrome - A
process where a photographic print can be made directly from a color transparency.
Collage - Collage
is from the French meaning "paste up". The combination of pieces of cloth,
magazines and other found objects to create artwork.
Collograph - This
name is derived from the word 'collage'. It is an image built up with glue and other
materials.
Color - When
light is reflected off an object, color is what the eye sees. The primary colors are red,
yellow and blue. The secondary colors are orange, purple and green.
Color Wheel - The Color Wheel describes the relationships between colors.
It is laid out so that any two Primary Colors (red, yellow, blue) are separated by
the Secondary Colors (orange, violet, and green)
Primary Colors are basic and cannot be mixed from other elements. They are
to color what prime numbers are to mathematics. One can mix two primaries to get a
Secondary Color. You will notice that each Secondary Color on the Color Wheel is bounded
by two primaries. These are the components that one would mix to get that Secondary Color.
Complementary Colors - Complementary colors are those which appear opposite to one another on a color
wheel. The complimentary colors are red and green, blue and orange, and yellow and
purple. These colors contrast
each other in the most extreme way possible. They also help to make each other more
active. In the Color Wheel illustration above, the complement of the color is used as text
in that section. This is to illustrate the opposite character of the color. The ratios and illustrations on the right of
the chalkboard are ideal amounts of color compliments according to Johannes Itten. He
believed that equal amounts of red and green are appropriate (1:1 ratio). Blue and orange
are different in value, so they their ratios need adjustment (5 blue:3 orange ratio). The
same is true of violet and yellow (6 violet:1 yellow). These ratios were probably devised
to counter the intensity of colors like yellow and orange.
§ Hint: All colors travel in waves within
light. Color Complements have drastically different wavelengths and, consequently, cause
some perception problems for a viewer if they are placed close to each other in a work of
art. The cones and rods of the eye cannot handle so much information, so we sometimes
detect a quivering or optical distortion when two complements are used near each other.
Composition - The
arrangement of lines, colors and form.
Conte - The
modern pencil lead invented by Nicolas Conte. It is a black, red or brown chalk.
Contour Drawing - Contour
drawing shows the outline of the subject, and not the volume or mass of an object. Blind
contour drawings are those created by looking only at the subject, and not the paper while
drawing.
Contrast - Contrast
is created by using opposites near or beside one another, such as a light object next to a
dark object or a rough texture next to a smooth texture.
BACK TO THE TOP
D
Distemper - This
painting technique involves the use of powdered colors that are mixed with glue size, or
such things as egg yolk.
Dominance - Dominance
is an object or color that stands out in relation to the rest of the painting.
Dry Brushing - Technique
used in paintings using more pigment then water.
Dye Transfer - This
is one of the most permanent color processes. This method gives maximum control of color,
balance and contrast for color prints or transparencies.
E
Easel - An easel
is used to support your canvas while painting. Can be a collapsible tripod, studio types
and as a combination sketch box unit. Some sketch boxes contain lids that serve as easels.
Edition - A
group of identical prints that can be numbered and signed by the artist.
§ Open Edition: An unlimited number of prints
§ Limited Edition: Prints that have a known number of impressions, and
are usually signed and numbered by the
artist.
Egg Tempra - A
water-base paint made with an egg yoke binder.
Elements of Art - Elements of art are the basic visual symbols found in the work such as lines,
shape, form, space, point, light, motion, direction, scale, dimension, texture and color.
Encaustic - This
ancient art uses colored wax for painting. This technique involves painting images onto
walls with pigments that are blended with wax. When used with heat, such as an iron, the
permanent color is burned into the wall, for good.
F
Fixative Spray - For
fixing charcoal drawing on canvas before painting. Fixative spray is available in spray
cans, or for use with mouth atomizer.
Form - An
element of art, such as you would see in a sculpture that has three dimensions.
Fresco - Pigment
is applied directly to damp plaster making this wall painting medium one of the most
permanent form of wall decoration.
G
Gesso - A white
priming ground to be used on a variety of absorbent surfaces where acrylic colors,
polymers, oil colors, tempera or casein will be applied. Dries within minutes to be
brilliant white and not yellow. Can be tinted with acrylic colors before application for
toned grounds.
Gesture Drawing - This
quick drawing captures the energy and movement of the subject. It does not necessarily
have to be realistic.
Glaze - Color
that is thinned to a transparent state and applied over previously painted areas to modify
the original color. (see also Underpainting)
Gold Leaf - Used
for gilding, gold or silver (for silver leafing) is beaten to extremely thin sheets.
Gouache (Tempera) - Opaque watercolors and the technique of painting with such colors using white to
make tints.
Canvas Giclée Prints -
description, terminologies, process
H
Half-tone - still receives direct light
but at an oblique angle, and therefore less intense
Highlight - Faces ;directly towards the
light source (A good artist usually will have one principal highlight and the other light
areas less intense.
Hue - Hue is
another word for color. The attribute which describes colors by name, i.e. red, blue,
yellow etc.
I
Impasto - A manner of painting where the paint is
laid on thickly so texture stands out in relief.
Impressionism - Impressionism
is referred to as the most important art movement of the 19th century. The term
impressionism came from a painting by Claude Monet. His painting was titled titled
Impression Sunrise. Impressionism is about capturing fast fleeting moments with color,
light, and surface.
Intensity - This
term is used to describe the brightness, or the dullness of a color.
Intermediate colors - Obtained by mixing adjoining Primary and Secondary colors.
L
Line - A line is an identifiable path of a
point moving in space. It can vary in width, direction and length.
§ Horizontal lines run parallel such as === - They serve to express
peace, restfulness.
§ Vertical lines run up and down such as ||||| - They serve to slow the
eye down and create visual interest when spread apart in an uneven manner.
§ Diagonal lines are slanting lines such as \\\\\ - They serve to express action.
§ Angled lines are a combination of diagonal lines such as /\/\/\/\/
><<> They serve to express instability.
§ Curved lines are curly and express movement such as ~~~~~
Linseed Oil - Used
as a medium. The traditional "binder" for oil colors.
Lithograph - This
is a printing process. A small stone, or metal plate is used. The printer, usually with
the artists supervision covers the plate with a sheet of paper which are then run through
the printer.

of art such as clay, paint or pencil. Describing more then one art medium is referred to
as media. Any substance added to color to facilitate application or to achieve a desired
effect.

moisture in them evaporates, such as clay or modeling paste for oil and acrylic painters.
Some do not harden, such as plastecine and can be used again.
Monoprint - A
print that has the same underlying common image, but different design, color or texture.
Monotype - A one
of a kind print made by painting on smooth metal, creating a texture that is not possible
to paint directly on paper.

Newsprint - This
paper comes in large sheets, and is inexpensive. Newsprint will eventually yellow, and is
not a good choice for preserving artwork. Pen and market will bleed through newsprint.
O
Oil Cup - A container that can be clipped to your
oil palette. One cup for the medium, the other cup for the brush cleaner.
Oil Paint - A
definition by Winsor & Newton state: "Oils are one of the great classic media,
and have dominated painting for five hundred years. They remain popular for many reasons:
their great versatility, offering the possibility of transparency and opacity in the same
painting; the lack of color change when the painting dries; and ease of
manipulation."

unify a composition.
Rhythm - When
the regular repetition of particular forms or elements occurs in a work of art, that work
is said to have rhythm. It suggests motion.
S
Secondary colors - Orange, Violet, Green. Each
color is midway between the Primaries from which it can be mixed.

| LAYERS IN PAINTING |
A traditional oil
painting is created in layers from the raw canvas to the final highlights. While newer
materials (including acrylic gesso) have shortened the steps for many artists, some still
prefer the time honored way of creating an oil painting that will survive the centuries.
§ 1. The canvas, stretched
over wooden supports, is traditionally a heavy linen or cotton. Heavy linen canvas has
been in use for centuries as a painting support. The tightness of the weave will determine
the smoothness of the surface. The canvas is stretched evenly around well squared wood
stretcher bars and attached with brads or staples . Solid boards or panels are also
traditional surfaces but the subsequent painting layers are the same.
§ 2. The raw canvas is
sealed with a sizing made of rabbit skin glue. The glue comes in a granular form and must
be carefully dissolved in hot water. (The sizing has a quite unpleasant odor.) After
dissolving, the glue is allowed to cool and form a jelly after which the strength of
adhesion is tested. The size is then reheated slightly and painted on the canvas while
warm. The glue sizing makes the canvas less absorbent by sealing the pores between fibers.
§ 3. Priming, also known as
ground, is traditionally a lead white paint that is the base for the painting. (Lead
bearing paint is dangerous and must be used very carefully) The ground must be absorbent
enough to provide a 'tooth' for the paint, so that the paint adheres well but not too much
that it drains oil away from the surface and cause dull spots in the painting. The artist
may use several layers of priming, sanded between layers for a smooth painting surface
(for portraits).
§ 4. A toned ground is a
stain over the white priming. This provides the artist with a warmer color under the
painting and sets the tone for the painting. The stain is usually a diluted earth color
such as raw sienna or burnt umber thinned with turpentine. A transparent ground is called
imprimatura and allows light to reflect through paint layers making for more luminous
colors in the finished painting. A toned ground must be very dry before painting over it
§ 5. The underpainting is a
toned drawing in oil that is the beginning of the painting itself. The artist uses an
underpainting to develop the relationships of dark and light in the composition and
balance warm and cool areas. Sometimes the colors used are unrealistically intense in
order to influence the colors of the next layers. This is especially true when the artist
is painting in transparent layers (glazing). These first steps are painted with colors
thinned with turpentine.
§ 6. The artist continues to
build on the underpainting in subsequent layers to complete the painting. Renaissance
artists used thin layers of transparent colors carefully layered to build luminous color
effects. Each layer will have a little more oil in the paint mixture so that the painting
will not crack as it dries.
§ 7. When the painting is
finished and has dried at least six months, the artist will protect the surface of the
painting with damar varnish in two thin coats. This layer of varnish can be removed years
later when the surface needs to be cleaned. |
