Chapter 1 ✦ Introducing Photoshop CS2
Another advantage of drawings is that they take up relatively little space on a hard
drive. The file size of a drawing depends on the quantity and complexity of the
objects the drawing contains. Thus, the file size has almost nothing to do with the
size of the printed image, which is just the opposite of the way bitmapped images
work. A thumbnail drawing of a garden that contains hundreds of leaves and petals
consumes several times more space than a poster-sized drawing that comprises
three rectangles.
When to use Photoshop
Because of their specialized tools and methods, painting programs and drawing
programs fulfill distinct and divergent purposes. Photoshop and other painting
programs are best suited to creating and editing the following kinds of artwork:
✦ Scanned photos, including photographic collages and embellishments that
originate from scans
✦ Images captured with any type of digital camera
✦ Still frames captured from videotape or film
✦ Realistic artwork that relies on the play between naturalistic highlights,
midranges, and shadows
✦ Impressionistic artwork and other images created for purely personal or aes-
thetic purposes
✦ Logos and other display type featuring soft edges, reflections, or tapering
shadows
✦ Special effects that require the use of filters and color enhancements that you
simply can’t achieve in a drawing program
When to use a drawing program
You’re probably better off using Illustrator or some other drawing program if you’re
interested in creating more stylized artwork, such as the following:
✦ Poster art and other high-contrast graphics that heighten the appearance of
reality
✦ Architectural plans, product designs, or other precise line drawings
✦ Business graphics, such as graphs, charts, and diagrams that reflect data or
show how things work
✦ Traditional logos and text effects that require crisp, ultrasmooth edges
✦ Brochures, flyers, and other single-page documents that mingle artwork,
logos, and body-copy text (such as the text you’re reading now)
