Graphics
Programs
- Are more complex
- Require practice to
become adept with them
- Promise and deliver
much
- Usually can’t jump
right in and get started
- Think before you
leap can be important
- Save time and
possibly money if pre-plan
Choosing
an Image Size
Depends on what your
final use will be
- Computer screen
- Print material
- Web
If computer—640x480
- Must plan for the
least able
- Resolution—72dpi
(normal for most computers)
If printing
The dpi more
important 300x300 or 600x600
Memories…
Remember your RAM
Images with high
resolution take up more memory
- 72dpi =
4"x6" (about 385KB compressed)
- 300 dpi = full
screen (6MB compressed)
Downsizing results in a
better image than upsizing
- Small to large—poor
quality
- Large to small—results
much better
Image Type
Image type—number of
colors (color resolution)
If scanning
- Use the highest
setting available for photographs
- Use lower setting
if work is black and white
Scanners
Scanning software will
normally adjust the number of colors based on the type of image
Keep copy of original
image in the highest resolution in case you need to change later
Changing color
resolution over and over degrades image quality
Image Type
Depends on the image
being created and the purpose
Start with high color
resolution
Especially if you
want to use effects
Set the width, height,
and resolution in New Image dialog box
Start with 16.7 million
colors—that way you can use all the tools and downgrade later

Avoiding
Aliased Images
Jagged edges are
aliased
Result of taking a
analog shape and digitizing it (circle)
Curves like those in
the circle are made up of a grid of pixels
- Not possible to
create a curve without the jagged look
- Process of
anti-aliasing gives smoother appearance
Anti-aliasing uses
mathematics and shades of color to fool the eye into believing the edge is
smooth
Brush Tips
Select the Paint Brush
tool
Use the controls in the
Brush Tip palette to set the various options
Draw on your image to
get the feel of the various brush tip options
- Brush preview—upper
left corner of the Brush Tip tabbed palette
- Shows what brush
looks like and gives you idea of the effect you will get with it
Lower opacity—can see
previous lines drawn if lower enough (can replicate the masters)
