The Pareto Principle in Photography

  • The Pareto Principle states that 80% of results come from 20% of the effort.
  • Focus on the most important aspects of photography to achieve impressive outcomes quickly.

Core Photography Concepts to Master in 10 Minutes

1. ISO (International Standards Organization)

  • Definition: Sensitivity of the camera's sensor to light.
  • Higher ISO = more sensitivity but also more noise/grain.
    • E.g., ISO settings: 100, 200, 400, 800, up to 25600.
  • Best Practices:
    • Use the lowest ISO possible to maintain image quality.
    • Outdoor lighting: ISO 100.
    • Shade: ISO 200.
    • Indoors: ISO 400-3200 depending on light availability.

2. Aperture

  • Definition: Size of the opening in the lens, measured in f-stops.
    • Smaller f-number = larger opening = more light.
    • Larger f-number = smaller opening = less light.
  • Aperture & Depth of Field:
    • Lower f-stop = smaller depth of field (blurry background).
    • Higher f-stop = larger depth of field (more in focus).
  • Choosing Aperture:
    • Portraits: f2 or f2.5 (low depth of field).
    • Group shots: f3.5 to f4 (greater depth of field).
    • Landscapes: f16 to f22 (everything in focus).

3. Shutter Speed

  • Definition: Amount of time the shutter is open, measured in fractions of a second.
  • Impact on Motion:
    • Slower shutter speeds result in more motion blur.
    • Faster shutter speeds freeze motion.
  • Common Settings:
    • Portraits: 1/250 to 1/500 seconds to avoid blur.
    • Sports/action: 1/800 to 1/1000 seconds to freeze action.

Photography Scenario Workflow

  1. Set ISO: Start with the lowest setting based on the available light.
    • Outdoors: ISO 100-200.
    • Indoors or low light: Adjust upwards as needed.
  2. Set Aperture: Based on the depth of field required for your subject.
  3. Set Shutter Speed: Based on the motion you want to capture.

Troubleshooting Common Issues

  • If image is too dark:

    1. Slow shutter speed (but watch for blur).
    2. Lower aperture (if depth of field allows).
    3. Last resort: raise ISO.

  • If image is too bright:

    1. Lower ISO first.
    2. Increase shutter speed.
    3. As a last step: adjust aperture (maintain depth of field if possible).

Final Thoughts

  • Understanding ISO, aperture, and shutter speed helps troubleshoot images effectively.
  • Charts available for quick reference (screenshot recommended).
  • Learning these principles provides a foundational understanding necessary for more elaborate photography techniques.
