INTRO TO MMA MODULE 2

Computer Graphics

means drawing

pictures on a computer screen.

Digitization

is the conversion of

an analog signal or code into a

digital signal or code.

any analog material into electronic storage,

including sound and video.

Analog Signal

is any

continuous signal for which the

time varying feature (variable) of

the signal is a representation of

some other time varying

quantity.

Digital Signal

is a digitized

analog signal.

Scanning

image-based analog material into digital form.

Graphic Design

is the business of

making or choosing marks and arranging

them on a surface to convey an idea.

3 Main Roles of Graphic Design:

a. Identification

b. Information & Instruction

c. Presentation & Promotion

Identification

To say what something is, or where it came from

Information and Instruction

To indicate the relationship of one thing to another in direction, position and scale

Presentation and Promotion

To catch the eye and make its message memorable

7 Elements of Art

line, shape, form, color, value, space, texture

Transparency

A condition in which two or more surfaces

or substances are visible through each

other

– construct thematic relationships

– Compositional device

• Soften edges, establish emphasis,

separate competing elements

Layering

Compositing through the ability of having

different levels in one digital document

Principles of Art

1. Balance

2. Focus/Emphasis

3. Gradation/Contrast

4. Harmony/Unity

5. Movement

6. Pattern

7. Proportion

8. Repetition

9. Rhythm

10. Variety

Raster Images

are comprised of individual blocks of

color called pixels.

Resolution Dependent

The size of the pixels depends on the image’s resolution

Digital Images

are electronic snapshots taken of a

scene or scanned from documents, such as

photographs, manuscripts, printed texts, and artwork.

Resolution

is a measurement that determines how

many pixels get packed into a given space, which in

turn controls how big or small they are.

Bit

is the smallest unit of

measurement that computers use to

store information

Bit-depth

which controls how much color

information that pixel can hold.

Anti-aliasing

Displaying smoothly drawn curves on a pixelated display

can produce horribly jagged edges ("jaggies"). One

solution to this is to blur the pixels on a curve to give the

appearance of a smoother line. This technique, known as

anti-aliasing, is widely used to smooth the fonts on

pixelated computer screens.

Vector Images

are made up of points and paths that form shapes;

these shapes are then filled and stroked (outlined) with color.

Resolution Independent

Paths are based on mathematical equations that tell monitors and

printers exactly how to draw the image. Because there aren’t any

pixels involved, you can make vector images as big or small as you

want, and they’ll still look as smooth and crisp as the original.

3D Graphics

An object that has height,

width and depth, like any

object in the real world.

3D Imaging

is a

technique used to record and

display 3D (three dimensional) images

or an illusion of depth in an image.

Stereoscopic images

provide spatial

information that trick a user's brain into

believing and seeing depth in the

images.

Visual Identity

A brand is a relationship between a business or

organization and its audience. A brand identity is how

the organization communicates its personality, tone and

essence, as well as memories, emotions and

experiences. Visual identity graphic design is exactly

that: the visual elements of brand identity that act as the

face of a brand to communicate those intangible

qualities through images, shapes and color.

User interface (UI)

is how a user interacts with a

device or application.

UI design

is the process of

designing interfaces to make them easy to use and

provide a user-friendly experience.

Publications

are long-form pieces that communicate

with an audience through public distribution. They have

traditionally been a print medium. Think books,

newspapers, magazines and catalogs. However, there’s

recently been a significant rise in digital publishing.

Environmental graphic design

visually connects people

to places to improve their overall experience by making

spaces more memorable, interesting, informative or

easier to navigate.
