DSLR intro

  1. Mirror system inside lets you preview through the viewfinder the same image that is being captured on film/sensor
  2. Less than 21 mm is for extreme wide angle and for architecture
  3. zoom vs. focus
  4. HIGH ISO value means the sensor will be MORE sensitive to light, meaning it will take LESS LIGHT to get the right exposure
  5. The shutter in a camera is half a circle (180 degrees)
  6. camera shake: occurs with a shutter speed slower than 1/ [focal length] of a second
  7. fast lens has bigger maximum aperture 
  8. longer lenses APPEAR to have a shallower depth of field because they are magnifying the subject, which flattens the perspective and makes our eyes think the DOF is shallower
  9. Setting the “correct” white balance setting tells the camera how to make your whites and grays neutral, without any color tint
  10. camera does almost everything BUT lets you choose brightness, depth of field, picture style by pressing the Q button
  11. M (Manual)– you choose everything
  12. Tv (Shutter Speed priority) – you choose shutter speed, camera chooses appropriate aperture
  13. Av (Aperture priority)– you choose aperture, camera chooses appropriate shutter speed
  14. A-Dep (Automatic depth of field) – camera chooses aperture, shutter speed combo to get best DOF
  15. P (Program) – camera sets shutter speed and aperture, but you can choose ISO, AF/MF, white balance 
  16. Digital cameras that resemble 35mm film cameras
  17. one major way that DSLRs are different from consumer “point and shoot” cameras or phones: detachable lenses​
  18. ​prime lens are only one focal length
  19. zoom lenses are variable focal lengths
  20. if you are buying a camera and the price seems really low, make sure the price includes a lens
  21. 21-35 mm are for Wide Angle ​and for Landscape
  22. Lenses must be properly cared for
  23. Metaphors to understand how exposure is determined by window, garden hose​,tanning
  24. to describe sensitivity of digital sensors in digital cameras
  25. more available light is lower ISO​, less available light is higher ISO
