Master Class

Fundamental rules of optics and composition.

01. Sunny 16


The Context: You have no light meter.

The Rule: On a sunny day, set aperture to f/16. Your shutter speed should match your ISO (e.g., ISO 200 = 1/200s).

02. Rule of Thirds


The Context: Your photos feel boring.

The Rule: Never place the subject in the dead center. Place them on the intersection lines of a 3x3 grid.

03. ISO Logic


The Context: Choosing your film roll.

  • 100-200: Bright Sun
  • 400: Overcast / Interior
  • 800-3200: Low Light / Grainy
