Study Notes

Flowcharts

  • Flowcharts visually represent processes, systems, or algorithms using symbols and arrows.
  • Different flowchart types exist, including:
    • Process Flowchart: Shows steps in a process, useful for industry workflows.
    • System Flowchart: Illustrates data flow in a system, common in software design.
    • Data Flow Diagram (DFD): Highlights data movement in a process, showing inputs, outputs, and storage.
    • Program Flowchart: Used in programming to depict problem-solving logic.
    • Workflow Flowchart: Represents business workflows and decisions.
  • Common symbols include:
    • Oval: Start/end of a process.
    • Rectangle: A process step.
    • Diamond: A decision point.
    • Arrow: Flow direction.

Fundamentals of Technical Drawing

  • Technical drawing precisely depicts objects for engineering, architecture, and design.
  • Types of technical drawings include:
    • Charts: Graphical representation of data/processes.
    • Layout Plans: Spatial arrangements (e.g., construction).
    • Schematic Diagrams: Show component connections (e.g., electrical circuits).
    • Block Diagrams: Clear system representation using blocks (e.g., electronics).
    • Loop Diagrams: Depict loops in control systems (e.g., temperature).
  • Importance: Communicates design, provides construction instructions, and ensures accuracy.
  • Tools include:
    • Manual: Rulers, protractors, compasses, T-squares.
    • Digital: CAD software (AutoCAD, SolidWorks).

Fundamentals of Digital Imaging

  • Digital imaging is creating/manipulating visuals digitally.
  • Key concepts include:
    • Resolution: Measured in pixels (e.g., 1920x1080); higher resolution, sharper image.
    • File Formats:
      • JPEG: Compressed, widely used.
      • PNG: Supports transparency.
      • TIFF: High-quality, uncompressed.
    • Color Modes:
      • RGB: For digital screens.
      • CMYK: For printing.
    • Image Compression: Reduces file size without much quality loss.

Image Editing

  • Image editing alters images using software.
  • Common techniques include:
    • Cropping: Removing unwanted parts.
    • Resizing: Changing dimensions.
    • Color Correction: Adjusting brightness, contrast, and saturation.
    • Retouching: Removing imperfections.
    • Layering: Combining multiple images/effects.
  • Popular software includes Adobe Photoshop, GIMP, Canva, and Lightroom.

Mobile Photography

  • Mobile photography uses smartphones to capture images.
  • Tips for better mobile photography:
    • Use natural light.
    • Use the rule of thirds for balance.
    • Focus on composition (leading lines, symmetry, framing).
    • Experiment with angles.
    • Use editing apps (Snapseed, Lightroom Mobile).
  • Key smartphone camera features include:
    • HDR mode: Combines multiple exposures.
    • Portrait mode: Blurs background.
    • Night mode: Captures low-light photos.
    • Macro mode: Focuses on small objects.
