• Keep Facebook for outside class.
• Mobile phones switched off // or to airplane mode
to record or use camera in class so we can all
support each other to be present.

• Have fun
3. Laptop Loans
• If you need a laptop
temporarily (ie. yours has
broken down or you need
one for a project) UTS loans
laptops for 1 week at a time.
• Go to the UTS: IT Support
Centre desk on level 4 (entry
level in the engineering
building (bldg 2) - entry
through tower building.
4. USBs: 8MB or or more

24. Raster and Vector Images
• Raster • Vector
• Created by a mathematical formula which
• Are measured in dpi (dots per inch) forms smooth lines, curves and geometric
objects
• Resolution dependant: when scaled,
the pixels get larger and the image • Resolution independent – show examples
will become less clear with jagged
edges • Scaled up or down without image
deteriorating, they remain sharp and clear
• Edited using image editing software, • Make excellent line drawings, DDS, logos,
Photoshop. type, t-shirt images for sportswear, etc.
• Much smaller file size than bitmap.
• Best results – scan and work at the
correct resolution and size from the • Specs and flats ideal to send via e-mail
beginning
• Once downloaded can be scaled to required
size
25. The following example shows the difference
between a raster image and a vector image.
• Raster • Vector Image
26. Selection
• Raster selection
• Vector Selection
• Complex, computer doesn’t know that
all the pixels are part of the same
object.
• Just coloured dots according to the
computer
• Simple, a matter of clicking on the
shape to select individual parts
• Easier to edit
28. Image Modes:
RGB
(Red,Green,Blue)
The primary image mode for
graphics is RGB You should be aware
of the other modes though.
Is faster to work with than CMYK, as
RGB creates a smaller file size
making it perfect for web.
The human eye perceives colour as
RGB; scanners and digital cameras
capture colour information in RGB;
computer monitors display colour as
RGB.
29. CMYK
(Cyan,Magenta,Yellow,Black)
Colour printers generally use a
mixture of different coloured inks to
create the range of colours needed.
RGB images must be converted to
CMYK for commercial printing
When an image is converted to
CMYK some of the brilliance of the
RGB gamut (range) of colours will be
lost, so the image will have a duller
appearance
30. Resolution
Before scanning an image or taking a photo to use in Illustrator the required
resolution and image mode (RGB, CMYK, Grayscale) should be determined.
Choose:
300dpi for commercial printing of
books, glossy magazines and brochures.
150-200dpi for laser and inkjet printers
(home/office printers) make a test print to clarify
the best resolution for your printer
72-96dpi for e-mail attachments, the web, PowerPoint and multimedia
31. Major changes to resolution after you have started
may result in loss of detail and colour
The larger the dpi the better the quality of the shot

It is used to create technical sketches in the industry and is the go to

that you eventually LOVE it!
Editor's Notes
As you can see from the Sydney Opera House example, the raster image looks more realistic as it is easier to create a realistic image out of thousands of coloured dots than it is with a collection of coloured shapes. Both formats have their advantages however. In the next example, the top portion of the highest sail on the opera house has been enlarged considerably.
Good for complex artwork and realistic images such as photos. Vector graphics can also be a little easier to edit. As the picture is made of shapes, it is easier to select and edit individual parts. For example, in both of the examples below, a sail of the opera house has been selected. In the vector example on the right it was a simple matter of clicking a shape to select it. With the raster graphic on the left, however, it was a much more painstaking process as the computer doesn’t know that all of those pixels are part of the same object. It’s all coloured dots as far as the computer is concerned so applications like Photoshop need to include complex selection tools to assist the user in selecting parts of an image.
In this example, you can see the decrease in quality with the raster graphic. If you zoom in or enlarge a raster graphic, then the individual pixels become clearly visible. Since the vector graphic is made out of shapes, you can resize or zoom in as much as you want and the quality will remain unchanged.
