Art and ICT: Connections and possibilities
The computer provides a safe
space for the drafting of ideas, visual as well as written. There are certain
limitations on this: a mouse is not a good drawing tool, computer
screens/printouts have limitations of size, resolution, colour. Nevertheless,
if the art activity is appropriate for the ICT medium, it can allow all kinds
of new creativity.
Computer-appropriate
projects
Using software
to design:
Pictures which involve
manipulation or distortion of shapes. The computer excels at numerical
operations, so these kinds of effects are very easy.
Pictures which involve
substitution of colours. The ability to try out twenty different colour-ways
for a fabric design in as many seconds.
Pictures with repetitive
elements (tiling). Many programs allow you to select a small area and tile it,
sometimes with rotation and altered layout
Animations. The computer can
reduce the repetitive copying required in animation.
Transformations
of existing visual material:
Scanned pictures, from
painted/drawn or printed sources. Work can be digitised using a scanner, and so
can move in and out of the electronic medium.
Scanned natural materials:
fabrics, leaves. These copyright-free resources can provide many unexpected and
rich starting points for graphic work.
Downloaded pictures from CD
ROMs or Internet. Most of the works of major artists are available somewhere on
the Internet, and can be used as starting points for your own work. If you are
working commercially, copyright clearance will be necessary before you can
publish work derived from another artist.
Digital photographs. Images
from the environment¾indoors
and outdoors¾can be used immediately
on the computer screen.
¾all these can be
Electronically collaged,
combined and recombined. Areas may be selected, copied, moved around, rotated,
or placed from one image into another.
Changed in scale or size.
Zooming in allows you to work dot by dot, or a very small picture can be ‘blown
up’ to reveal unexpected texture, detail or ‘pixellation.’
Modified in colour or
‘texture.’ The colour of the picture is open to all kinds of changes:
inversion, increase in contrast and saturation, substitution of one colour for
another, reduction to monochrome, application of artistic effects…
‘Painted over’
electronically. The picture can be changed manually using brushes, smudge tools
and so on from your graphic program
Distorted: stretched,
warped, re-mapped.
Tiled. An area can be
selected then repeatedly copied. There are several pieces of software designed
to create tiled patterns from picture sections
Animated. Images may be
transformed into animations to use in web pages or transfer to video
Linked with text. Letters
and other textual elements may be merged with the graphic to create further
designs
Exchanged over the Internet.
This opens possibilities of collaboration on graphic work over any distance,
and the gradual development and change of a piece through many different
artists
Published on web-sites. A
potential world-wide audience for your graphic work.
Printed out, developed in
other media. The electronic graphic may be a design for a piece in the ‘real
world,’ the print out may be cut up, distressed, collaged, enlarged on
photocopiers… the computer is only a tool, not a creative artist in its own
right.
Specific
software
Adobe Photoshop. The market
leader for professional graphic work. Very expensive.
PaintShop Pro. A powerful
package available on the University network.
Microsoft Paint. A basic but
useful paint package available on all Windows computers.
Microsoft Photo Editor. This
comes with Microsoft Office, and has a large number of very powerful artistic
effects and transformations. Not a paint package.
Irfan View. A small free utility program, excellent for speedy picture editing: converting, cropping, re-sizing etc.
Picasa from Google - organise pictures and carry out basic but powerful editing tasks - crop, effects, collage, enhance etc. Free!
Children’s
Software
Dazzle. An easy-to-use paint program with artistic effects, tiling and much more.
On-line: Artrage, Bomomo, Mr Picassohead
Colour Magic. The RM
Window-Box paint package. Good for symmetry work.
KidPix Studio. A CD ROM with
all kinds of extraordinary paint, video, animation projects, all with
appropriate sounds.
Picture
file-types
Pictures are stored on
computers in many different forms, and although it may seem a bit technical
it’s as well to know a little about them:
Pixel Pictures.
Pictures made up of dots (pixels) are very common. Often called Bitmaps
(because each ‘bit’ of the picture is ‘mapped’ to a different colour.) When you
enlarge one of these pictures too much it breaks down into a pattern of dots,
or pixels.
On PCs, each file has a
suffix, a group of letters after the name which tells the computer what sort of
file it is.
Windows bitmap files picture.bmp
Vector drawings.
These pictures are made of lines which the computer ‘colours in’ each time they
are drawn. When you enlarge these pictures they retain their integrity. Acorn:
Draw files. Publisher clip art is mostly wmf files.
Windows Metafiles picture.wmf
Windows enhanced
metafiles
picture.emf
Compressed
pictures. If a picture file is too
large it may take hours to get from one computer to another down the narrow
‘pipe’ of your phone line. Pictures of the previous types can be compressed to
a very much smaller size, making them much easier to move from one machine to
another, or over the Internet. The file is squashed/compressed before sending
or storing, and then reconstituted by your graphic software to its full size.
JPEG Files picture.jpg
These are highly compressed
pictures and have become the most common format on the Internet. They are
supported by Acorn, PC and Apple and can be moved seamlessly between platforms.
They can be opened using Internet Explorer or Netscape, and will be accepted by
all recent word-processors and DTP programs. They do, however, lose quite a bit
of fine detail in the process, so should not be used for images which are going
to be professionally or photographically printed.
TIFF Files picture.tif
‘Tagged Image Format’ files
are also common on the Internet. They are not compressed like JPEG files.
‘Graphic Image Format’ files originally patented by
Compuserve. Compresses the information by assigning each colour a specific
number. A little picture with very few colours will therefore create a very
small file.
EPS Files picture.eps
Encapsulated Postscript
files are used to transfer accurate font information within a graphic, and are
handled by programs such as Pagemaker.
