Boot Camp 2013: Day 2

  1. 1. Camera/Sound Boot Camp: Day 2 Day 2 Day 2
  2. 2. Agenda • Housekeeping • Insurance Questions? • Review Week 1 • Depth of Field • Color Temperature • Camera “Field Practice”
  3. 3. How do you eat an elephant?
  4. 4. One bite at a time.
  5. 5. After this lab, you will be able to •List three things that affect depth of field •Identify different color temperatures •Understand perspective distortion •Adjust the shutter, f-stop, and focus on the EX1 •Set the white balance on the EX1 •Use zebras to prevent overexposure •Use peaking to assist focus
  6. 6. Exposure Amount of light that a given medium requires for image reproduction
  7. 7. Three determinants of exposure •F-Stops •Shutter speed •Sensitivity
  8. 8. Shutter Speed Aperature = how much light is allowed to strike the sensor Shutter speed = how long the light is allowed to strike the sensor
  9. 9. Three elements of Depth of Field •Aperture •Camera/subject distance •Focal length
  10. 10. Shallow Deep
  11. 11. Perspective distortion extension distortion wide-angle distortion compression distortion telephoto distortion
  12. 12. 28mm lens 50mm lens 70mm lens Photos taken using a 35 mm still camera at a constant distance

  17. 17. 28mm28mm
  18. 18. Clever uses of compression distortion
  19. 19. Color Temperature Color temperature is measured in Kelvins (k)
  20. 20. Color Temperature Basics Indoor lighting is 3200 Outdoor lighting is 5600 3200k has an orange 5600k has a blue kelvins. kelvins. hue. hue.
  21. 21. Three determinants of exposure •F-Stops •Shutter speed •Sensitivity
  22. 22. Three elements of Depth of Field •Aperture •Camera/subject distance •Focal length
  23. 23. Color Temperature Basics Indoor light is 3200 Outdoor light is 5600 3200k has an orange 5600k has a blue kelvins. kelvins. hue. hue.
  24. 24. Warm versus Cold
  25. 25. White Balance

  27. 27. PMW-EX1
  28. 28. Battery & Power On
  29. 29. Standard Format Settings Shutter 1/48 Country NTSC Video Format (EX1) HQ 1080/24P Video Format (EX1-R) HQ 1920/24P
  30. 30. Press: Menu Scroll to: OTHERS Select: Country Confirm it is NTSC
  31. 31. Standard Format Settings Shutter 1/48 Country NTSC Video Format (EX1) HQ 1080/24P Video Format (EX1-R) HQ 1920/24P
  32. 32. ND Filter (Neutral Density Filter)
  33. 33. 0dB
  34. 34. 1/48 Technical explanation: “With a traditional shutter angle of 180°, film is exposed for 1/48 second at 24 frame per second.” Simple: Looks better (more like film = more cinematic)
  35. 35. White Balance You have three options –PRST: Preset mode (a factory setting of 3200K)A: Memory A mode B: ATW or Memory B mode To store a temperature: 1.Point the camera at a white object that is matte (non-reflective) and covers 80% of the frame. 2. Once you have selected your white matte object, turn the white balance switch to “A” 3. Press the white balance button.
