Types of digital media products
  • Graphic digital media
  • Desktop publishing
  • Graphic design
  • Audio digital media
  • Audio sequences
  • Music compositions
  • Video and animation digital media
  • Animation sequences
  • Video production

Graphic Digital Media
  • Desktop publishing
  • Allows you to create any type of . . (eg.
    , .. and cards)
  • Allows you to combine data (text and graphics)
    from a variety of sources to create your own page
    . with precise control over all objects on the
    page.
  • Uses digital images extensively.
  • Examples Adobe InDesign or PageMaker, MS
    Publisher, QuarkXPress, Print Shop

Graphic Digital Media
  • Graphic Design
  • Creates or edits images - used for diagrams and
    illustrations, photos, artworks and 3-D images.
  • Examples
  • Photoshop, PaintShop Pro (photography)
  • Illustrator, Freehand (technical drawing)
  • Corel Painter, TwistedBrush (artistic drawing)
  • Maya 3D, 3D StudioMax (3-D graphics)

5
Data Compression methods
  • Read pages 272 -273 of the text, then answer the
    following
  • What is data compression used for?
  • Name two hardware devices that sometimes have
    data compression built-in.
  • Name the two main methods used to compress
    digital data and briefly describe the features of
    each.
  • Name a program that uses each method of data
    compression.
  • Would you use lossy compression to reduce the
    size and transmission time of a very large
    word-processed document, spreadsheet or database?
    Explain why or why not.

6
Data transmission methods
  • There are two different ways of sending binary
    data between computers, or between computers and
    other devices (such as printers, scanners, etc).
  • Text Activity (pg 272)
  • Name the two methods of binary data transmission.
  • Describe how the binary data travels in each
    method.
  • Draw a simple diagram of each method.
  • List the advantages of serial data transmission
    over parallel.
  • When is it appropriate to use parallel over
    serial?

7
Bitmapped and Vector Graphics
  • What are
  • Bit-mapped graphics?
  • Vector graphics?
  • Explain the difference between Paint software and
    Draw software.
  • From the programs listed on the previous slide,
    name the
  • Paint programs
  • Draw programs
  • Answer Think questions 3 4 from page 97, Ware
    textbook.

8
Manipulating graphics data
  • Techniques used to manipulate graphics include
  • Resizing
  • Cropping
  • Special effects
  • Rendering
  • Use pages 102-105 of the text to describe these
    techniques, why they are used and how they may
    effect the image (eg. Memory size, quality of
    image).
