  1. 1. KAUST Community Photography Club Presents DSLR Camera Basics by Muhannad Abu-Ghdaib
  2. 2. Presentation Outline 1. Definition of a DSLR 2. DSLR Vs. Point & Shoot 3. DSLR Basics
  3. 3. What is a DSLR ? D: …. ? S: Single L: Lens R: Reflector camera
  4. 4. What does this mean? is a digital camera that uses a mechanical mirror system and a prism to direct light from the lens to an optical viewfinder on the back of the camera.
  5. 5. What is a DSLR ?
  6. 6. Point-&-Shoot Vs. DSLR • Viewfinder. • DSLR: Optical • P&S: Digital LCD or Optical Tunnel • Pros & Cons • Manual Control over almost everything! • Sensor size image quality (Noise) • Interchangeable lenses. • Size & weight • Bulkiness • Price…etc.
  7. 7. The Viewfinder
  8. 8. Point-&-Shoot Vs. DSLR Image Quality Canon 20D KM A2 ISO 200 ISO 200 Shutter Speed 1/320 Shutter Speed1/800 F11 F9
  9. 9. Point-&-Shoot Vs. DSLR Image Quality Canon 20D KM A2 ISO 400 ISO 400 Shutter Speed1/400 Shutter Speed 1/400 F11 F9
  10. 10. Point-&-Shoot Vs. DSLR Image Quality Canon 20D KM A2 ISO 800 ISO 800 Shutter Speed1/640 Shutter Speed1/3200 F11 F9
  11. 11. Point-&-Shoot Vs. DSLR Sensor Sizes •The Larger the sensor: •The better is the quality of the image. •The more is the area of the scene covered in the photograph. •The more expensive is the camera. •Canon 5D Mark II is a full frame camera that costs around SR12,000. •Common DSLR cameras sensors’ area are 62% of the full frame DSLRs. Their prices are between SR2,000 & SR5,000. •Full frame cameras have their own type of Lenses that are specially manufactured to suit their large sensors. •Point & Shoot Cameras have small sensors: ONLY 4% - 6% of the full frame Camera Sensors!
  12. 12. Point & Shoot are still good! Your eye and how it sees things is what make a picture a beautiful one. This photograph is taken by simple point & shoot camera, yet it is beautiful!

  14. 14. DSLR Photography • Parameters affecting the image: 1. Shutter Speed 2. ISO Speed 3. Aperture (f-number)
  15. 15. Shutter Speed • It is the time over which the shutter is open. • The Shutter: – A mechanical diaphragm that opens to allow light to impinge on (see) the sensor. • Affects Exposure. – Exposure is the amount of light falling on the sensor. • Measured in milliseconds (Short Exposure) and in seconds (Long Exposure)
  16. 16. Shutter Speed Short exposures: – 1/4000th of a second (Daytime). – 1/5th of a second (Low Light) • FEE MOSHKILA! :@ – Tripod – or use Burst Mood
  17. 17. Shutter Speed Long Exposures: • 1 Second • 30 Seconds • Bulb Mode • Day & Night shots

  23. 23. ISO Speed • I : International • S: Standardizing • O: Organization – It is a measure of the sensitivity of the sensor. • How fast a sensor (film or digital sensor) records the light it sees. • Ranges from 50 – 3200 128,000 • Larger range more EXPENSIVE!
  24. 24. ISO Speed • Affects: – Shutter Speed – Image Quality – LOWER IS ALWAYS BETTER! – 100 – 400 is good.
  25. 25. ISO Speed • See in the dark, when flash undesirable
  26. 26. ISO Speed
  27. 27. Aperture Opening • Controls the amount of light seeing the sensor. • Focus • Sharpness • Measured in f-numbers – Kit Lens f: 3.5 – 5.6 – Low f: 1.2, 1.4, 2.2 – High f: 5.6 - 22
  28. 28. The F-Number • It is inversely proportional to aperture. – F = Focal Length / Diameter of the aperture opening. • Use Higher F: – Landscapes – Details – High Lighting (noon time) • Lower F: – Better Bokeh (blurred background/foreground)
  29. 29. The F-Number • DOF: – D – Depth – O – Of – F – Field • Bokeh: – The blurred background • Lower F number, better DOF
  30. 30. The F-Number • High F-Number for Details
  31. 31. The F-Number • High F-Number for landscapes
  32. 32. The F-Number • Where to Read it?
  33. 33. Summery of Parameters Shutter ISO Speed F-Number Speed
  34. 34. Focusing • Focus Area • Focus Points
  35. 35. Focusing • Focus Points: – 9 – 11 – Up to 56
  36. 36. Focusing • Better focus • Don’t forget to adjust the f number • Manual Focus • Auto focus: – Press halfway until the circle stops blinking F-Number
  37. 37. Other Parameters • Metering • White Balance
  38. 38. Which mode is better? • Manual • Av: ( Aperture Value AV) or Aperture Priority.
  39. 39. Which mode is better? • Manual: – Use it when the camera is not predicting the right shutter speeds for low light conditions • Av: – I always use it!
  40. 40. Lenses • Focal Length: – Ranges from 10 – 500 mm? – The less the focal length, the wider the angle – Longer focal lengths, better bokeh (DOF). • F-Number. – Changes with Focal Length. – Prime Lenses • F-number Does not change
