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.
