Polarization photography

  1. 1. Polarization Photography
  2. 2. Polarization Photography Reduce Sun Glare Reduce Reflections Darkens Sky Increase Color Saturation Reduce Haze
  3. 3. Polarization Photography  Polarizing filters are used in photography and in certain kinds of sunglasses. But polarization is also used in digital watches and laptop screens. In this unit we will learn what polarization is and how polarizing filters can do amazing things with light.  Polarization is everywhere in daily life. It is an important principle enabling many familiar things to work the way they do, from sunglasses to digital watches and laptop screens.
  4. 4. Polarization Photography Without Polarizer Provides better Color Saturation  Darkens the sky With Polarizer
  5. 5. Polarization Photography Without Polarizer With Polarizer
  6. 6. Polarization Photography : Scattering Haze De-hazed
  7. 7. Polarization Photography : Reflections Reduce Reflections
  8. 8. Polarization Photography : Underwater Underwater pipelines and communication Offshore structures Recreational photography Underwater ROV/AOV
  9. 9. Light as Plane Waves Sinusoidal plane waves very good approximation.  Very useful for characterizing polarization.  I max I min θmax 180 o  Polarized Wave: Has only one preferred orientation.  Un-polarized Wave: Has no preferred orientation or has all orientations.
  10. 10. Classification of Polarization  Linear : Two orthogonal plane waves with same phase but possibly different amplitudes.  Circular: Two orthogonal plane waves with 90 deg phase shift but same amplitudes.  Elliptical: Possibly any degree phase shift with different amplitudes.
  11. 11. Linear Polarization
  12. 12. Circular Polarization
  13. 13. Crossed Polarizers
  14. 14. Elliptical Polarization
  15. 15. Polarized Sunglasses Reduce glare off the roads while driving
