Visual Communication

Graphics

  • Visual designs used to inform, illustrate, entertain (e.g., photos, brand designs, typography, infographics, memes)

  • Displayed on canvas, paper, walls, or digital screens

Elements of Design

  • Point: start/end in space; single point can convey meaning

  • Line: connects two points; suggests movement & direction

  • Color: light reflected; varies by hue, saturation (intense–dull), temperature (warm–cool); schemes—complementary, analogous, triadic

  • Value: lightness/darkness; builds depth

  • Shape: 2-D enclosed areas; geometric vs. organic

  • Texture: surface quality—smooth or rough

  • Space: area around/between elements; “breathing room” for focus

Principles of Design

  • Balance: symmetrical (even) vs. asymmetrical (uneven) visual weight

  • Emphasis: focal point stands out from rest

  • Movement: guides viewer’s eye & implies action

  • Pattern: unity through repeated elements

  • Proportion: relative size; influences realism & emphasis

  • Unity: overall harmony; too much sameness = dull

  • Variety: differing elements to maintain interest; excess causes clutter

Photography Essentials

  • Gridlines/Rule of Thirds: align subject with intersections for balance

  • Pose: adds story & dynamism

  • Lighting: natural/artificial/flash; angled light adds dimension

  • Focus: depth-of-field; for portraits, focus on nearest eye

  • Perspective: bird’s eye, eye level, worm’s eye change interpretation

  • Space: leave room for text or “fill the frame” to highlight subject

Image Manipulation Basics

  • Cropping: remove unwanted areas; improves framing & aspect ratio

  • Brightness/Contrast: overall lightness vs. difference between light & dark

  • Shadows/Highlights: dark vs. bright regions

  • Vignette: dark/light fade at edges to draw attention inwards

  • Filter: preset adjustments (warmth, saturation, tint, sharpness)

Digital Image Concepts

  • File attributes: size, type, physical dimensions, resolution (pixels\text{pixels})

  • Raster: pixel-based, resolution-dependent; one size

    • GIF (small animations), JPEG (compressed previews), PNG (transparent HQ), BMP (raw), TIFF (detailed editing)

  • Vector: resolution-independent, math-defined curves

    • AI (Adobe Illustrator), PDF (platform-independent display)

Infographics

  • Visual representation combining images, charts, text for quick, clear data

  • Purposes: rapid communication, simplification, engagement

  • Common types:

    1. List – text-focused topics

    2. Guide/Process – step-by-step instructions

    3. Comparison – side-by-side differences

    4. Mixed Chart – multiple statistical visuals

    5. Hierarchical – layered relationships

    6. Visualized Numbers – big numbers/icons for impact

    7. Photographic – image-driven storytelling

Typography Fundamentals

  • Typography: arranging text for readability & aesthetics

  • Typeface: letterform design (e.g., Times, Arial)

    • Serif: letters with end strokes; formal

    • Sans Serif: no strokes; modern, headings

  • Kerning: spacing between letters

  • Shadows & Strokes: add separation & visibility

  • Ligature: two letters combined as one symbol; affects legibility
