ISO

• Definition: Sensitivity of your camera's sensor.
  • Higher ISO: More sensitive to light (more grain/noise).
  • Lower ISO: Less sensitive to light (clearer images).
• Principle: Keep ISO as low as possible to avoid grain/noise.
• Examples with Sony A7R2:
  • ISO 100
  • ISO 200
  • ISO 400
  • ISO 800
  • ISO 1600
  • ISO 3200
  • ISO 6400
  • For fun: ISO 12,800 and 25,600.
• Camera Pricing: Higher-end cameras handle higher ISOs better.
  • Cheaper cameras: Usable up to 800 or 1600 ISO.
  • Expensive cameras: Usable up to 3200, 6400, 10,000+.
• Practical Usage:
  • Outside: ISO 100.
  • Shade: ISO 200.
