1. Graphics – Day 1

2. Why use graphics Different learning styles
Many things are hard to explain in text
Provides interest

3. Use relevant graphics
Graphic draws the eye First thing the reader will see on a page
Choose graphics that support and expand upon the text
Give the graphics the same look & feel
Use graphics appropriate to the audience

4. How relevant Questions to ask is:
What does the graphic add?
Why bother?
How does this enhance the material?
What happens if a large, but not relevant graphic is put on the page?
If the graphic is placed too low on the page what happens to reading the material?

5. Same look & feel
Give the graphics the same look & feel

6. All images are similar

7. Inserting graphics into text
Place after first text reference
Always use a caption
Figure captions go below Table captions go above
Don’t leave excess white space either before or within the graphic
Minimize use of boxes or lines around the graphic

8. Placement on the page
Graphic draws the eye First thing the reader will see on a page
If the graphic is placed too low on the page what happens to reading the material?

9. White space around graphic

10. Figures fit within the margins

11. What is perception difference?

12. Graphic numbering
Figures and tables are numbered separately (If it’s not a table, then it’s a figure)
Start both at 1 and continue to end of document
Folio numbering (1.3, 4.2) are only used when the document contains chapters

13. Graphic captions 3 parts
Figure or table number
Title
Descriptive text
Fig 3. Enrollment from Numbers were based on first day enrollment.

14. Good caption examples Figure 1. Average grade point by major.

15. Bad caption examples Figure 1.

16. Color

17. Color in graphics
Web has lots of colored figures, but most technical documents are produced in black and white.
Loss of color can create a gray blob.
Convert the graphic to BW with a image program, do not let the copier do it.

18. Parts of color Hue – Difference in the color
Blue vs yellow, light red versus dark red
Value – lightness or darkness
Saturation – intensity of a color

19. Gray scale 9 steps of gray Eye is best at lighter shades of gray
False color is really gray scale
Grays are converted to color
Easier for eye to see/compare colors

20. Color and BW graphic

21. Changing images to grayscale
Turn on picture toolbar.

22. Color in printing Each color requires a separate printing step
2 colors doubles the cost
Full color
Uses 4 inks
Most expensive printing process
Crisp color requires coated paper (more $$$)

23. Color touching color
Eye is very good at comparing two colors when they are close
Very poor at subtle differences when it cannot see the them or they are separated
Touching colors can be close to the same
The more separation, the more contrast
If not see at same time, use different color

24. Color contrast illusion
Diagonal rows are the same color

25. Color blindness About 10% of male audience is colorblind
Must watch the color choices, especially on graphs
Normal
Red-green
Blue-yellow

26. Line drawing vs. photos

27. Line drawing or photo Line drawing Photo Emphasis on specific parts
Can remove extra material
Photo
Gives better overall image
Contains lots of extra material

28. Power window switch

29. FedEx sort facility

30. Line drawings

31. Ethernet card images Note how shading helps
Take a picture of a Ethernet card

33. Bitmapped graphics
Word uses graphics that are bitmapped. You can reduce, but not enlarge them without losing clarity.
Bitmapped means they are made of lots of little pixels, with each pixel being one color.

34. Resizing
Programs can resize proportionally or not. Means both dimensions change equally.
In Word, use the corner handle bars.

35. Enlarged bitmapped graphic
