Drawings Are Original, Hand-made Art One of the biggest challenges
faced by an artist who does digital drawing is the fact that many people cannot
believe that the medium exists; they persist in thinking that the work is a
reproduction of some sort. It important to broadcast the message that, not only
can you draw on the computer, but what you produce is original, hand-made
art. There are many digital images, often called Giclées, on the market
that are created by photographic scan of a piece of art completed in another
medium, such as painting or pastel. Even though these images are produced
as limited editions and signed by the artist, they remain reproductions, not original
prints, because the originals were done in a different medium.
With a digital drawing, the art is created in the same medium that is used to
print it. It starts out as a digital file, and in the end that same digital
file drives the printer (an Iris inkjet in my case). So the drawing is an
original, not a reproduction. If it is editioned, the drawing becomes an original
multiple, ie., a fine art print, signed and numbered by the artist. To make an
analogy with a traditional print medium, the digital file is to the Iris print
as the crayon drawing on a litho stone is to the lithograph. The
Computer as a Creative Tool The computer is the most powerful creative
tool an artist can possess, and it is well on its way to revolutionizing the
making of visual art just as word processors have transformed the way most
of us write. Unique among all the various ways of creating art with pixels, digital
drawing expands the definition of computer art to include work of the size,
look, and level of detail of traditional media. (See Figure 1.) 
Figure 1. In the upper left is a charcoal drawing I did in 1982; in the lower
right corner is a digital drawing done 20 years later. Up close or at a distance,
it is very hard to tell which one is analog and which one is digital.
The
reasons to draw on a computer are many, the foremost being that it dramatically
expands creative freedom. First, thanks to Layers (see Favorite
Features below), the basic mechanics of drawing can become much more inventive.
Second, the fact that multiple versions of a drawing can be saved greatly
encourages risk-free experimentation. Third, not only can an image can have many
variations (black and white, colored, negative, larger, smaller, etc.), but
parts of one image can be copied into another image, either as a time-saver
or in order to create mysterious surreal effects. In addition to the creative
pluses, drawing on the computer enables the artist to combine the look of
unique work with the advantages of multiple copies. The artist can keep portfolio
copy of each piece for artistic reference, shows, and promotion and at the
same time reach the wider audiences enjoyed by printmakers. Being able to produce
an image in several different sizes also helps in adapting to the marketplace.
Last but not least, there is no dirt, no toxic fumes, no heavy-lifting. And
studio clean-up is accomplished with a tap of the stylus.
Favorite Features
Undo At the top of my list of favorite features is Undo.
Weak pencil strokes and other miscalculations can be instantly removed from
the image without altering any of the rest of it. In addition to correcting
mistakes, toggling back and forth between Undo and Redo
is a great way to test out ideas.
Layers My next favorite is Layers, which are analogous
to drawing on stacked transparent sheets. Sky can go on one layer; trees on
another; grass on a third; and if the trees need to be redrawn, the revisions
can be made without affecting the sky or the grass. Final nuances of shading can
also be separated onto their own layer, which facilitates a loose and spontaneous
beginning while preserving as much precise control as is needed at the end.
When the drawing is finished, the layers collapse seamlessly into one image.
Multiple Paper Textures, Infinite Brushes
Being able to combine multiple paper textures in one drawing to suggest various
types of surfaces is also a huge plus, as is the infinite number of brush
sizes and shapes. Using 800 pixel charcoal is comparable to roughing-in with
a janitors broom; push the slider the other way and suddenly the same
charcoal pencil is as sharp and fine as an etching needle; squeeze it and
you have a calligraphy tool. (See Figure 2.)
Tracing Paper Last but not least on my short list is the tracing
paper feature. With the drawing on the screen and the reference photograph
or sketch either side-by-side or minimized out of view, the tracing paper
button shows or hides the reference imagery as if it were on a light box under
the drawing. For artists who work with reference photographs, this means that
a lot of laborious cartooning can be by-passed. (See Figure 3.)
The Hardware The manipulation
of large digital files requires a reliable platform. After several years of trial
and error, the best solution resulted from using a Pentium III (dual 1GHz
Pentium III) computer originally designed to be a server. It runs
under Windows 2000 and allows the latest versions of both Corel Painter and
Adobe Photoshop to co-exist without choking on 100+ Mb files with all their
add-on masks and layers that vary widely throughout the course of producing complex
drawings in 24-bit color.

This picture shows the marks the charcoal brush makes on Synthetic Superfine
Paper at various sizes and also the calligraphic look of a squeezed rather
than round tip.

In the left window is a section of the reference photograph. The right window
shows the corresponding section of the drawing with tracing paper feature
turned on. (See Figure 5 for the same view with the tracing paper turned off.)
Figure 4. In the foreground is my Wacom tablet and stylus.
The key here is memory: 4 Gb of RAM (ECC) are needed along with fast (SCSI) drives.
I use three 17.5 Gb and one 80 Gb Seagates (10,000 rpm). A high-end video
board is also recommended, preferably one with dual monitor capability (from
ATI or Matrox), that can handle 21-inch monitors at 1280 x 1024 or higher
pixel resolution.
Drawing input is accomplished via a Wacom Intuos 9 x 12 tablet and
stylus. (See Figure 4.) Output, for proofing purposes only, is to an Epson
820 (6-head ink jet) photo printer. In order to assure that working proofs
from your desktop printer are the same as the image as it appears on the monitor,
the best approach is to set the default color space for both Painter and Photoshop,
including printer output, to the Adobe RGB (1998) standard, and to then calibrate
the monitor accordingly using Pantones ® ColorVision TM Spyder TM
monitor profiler.
The Software The best software
on the market for doing digital drawing is Corel ® Painter 7 TM because of
its Natural-Media ® simulation. Natural-Media means that the
combination of brush and paper texture are pressuresensitive, so that a hard
stroke is not only darker but pushes deeper into the paper grain while a light
stroke skims the surface just as in analog drawing. Other drawing programs
just produce lighter or darker strokes of identical patterns, which do not
look as convincing. Although Painter has decent photo-editing capabilities, Adobe
Photoshop ® is the premier piece of software for working on reference
photographs. About the Author
I do realist landscapes. I specialize in digital drawings and use my own 35 mm
slides or digital photographs for reference in their creation. The information
below will reflect this bias, but I hope people who work abstractly or expressionistically
or from life, the figure, or imagination will see how my methods can be adapted
to their style. Although I will only cover digital black-andwhite drawings,
please be aware that the software can produce the look of any two-dimensional
medium, from pastel to paint, watercolor to woodcut, and all in one image if desired.
