  1. How Can You Get Higher Quality Photos? Fangjun Shu July 20, 2007

  2. Outline • Familiar with our equipments • Preparations • Taking photos • Illumination • Camera setting (Shutter, aperture, iso…) • Focus • Click! • Use of accessories • Post processing • My suggestions

  3. Familiar with our equipments What do we have? • Cameras: • Nikon D70 6 M pixel digital camera (most often used) • PCO SensiCam QE DS camera • Panasonic VDR D100 DVD video camera • Security camera • Phantom high speed camera • Accessories • Lens (F-mount, C-mount and microscope lens with tube) • Borescope (30º with illumination ports) • Photo booth (with one tripod and two spotlights) • 67 mm filter set for the Nikon D70 digital camera (UV, fluorescent and polarizer filter) • Three F-mount extension tubes for taking magnified pictures (for the Nikon D70)

  4. Preparation • Equipment selection and preparation • Camera, tripod, photo booth, filter … • Background • If possible, please use the photo booth • Remove all unrelated objects from the view • Isolate the unrelated background using a light cold colored curtain or board, I personally prefer blue • Arrange the scene • Don’t “hide” your subject in distractions • Don’t let your subject occupy the whole picture • Don’t leave big unoccupied space in the picture • Put your subject a little bit off the center (1/3) • Keep the picture “balanced”

  5. Back 45º back Side Object Front 45º front Camera Illumination • Brightness • Measure • Compensation • Direction • 3D • Color temperature • White balance

  6. Illumination direction Ambient Flash 45º front spot light 45º back spot light Back spot light

  7. Camera setting Camera settings • Camera mode • Auto • Micro • “A” – aperture priority (F/#) • “S” – shutter priority (exposure time) • “M” – Manual (F/# and exposure time can change independently) • ISO

  8. F/# examples F/14 F/4.2

  9. 2 – ½ sec. 2” – 2 sec. 2 Shutter time examples 1/15 sec 1/80 sec

  10. ISO examples ISO 200 ISO 1600

  11. Focus Though manual focus is available for the camera, I suggest auto focus. It is usually more accurate. When using extension tube(s) for magnified picture, you’d better focus manually first then use the auto focus. There should be details in the auto focus window to ensure valid auto focus. The auto focus more sensitive to vertical lines in many digital cameras.

  12. Click! • If a tripod is not used, hold the camera correctly. Hold your breath while clicking. • When shooting static objects, take more photos than required. Review your picture on the camera and adjust camera settings accordingly (ISO, shutter, F/#, etc.) • I suggest use the continues shooting mode when taking pictures of moving objects.

  13. Use of accessories (Extension tubes) 1 tube Extension tubes 3 tubes original

  14. Use of accessories (circular polarizer filter) with CPL filter Original (with out CPL filter)

  15. Post processing • When we take pictures, we should do our best to ensure good quality. But … • If you can increase photo quality via post process, why not? • With Photoshop, you can do almost everything you can think of. But don’t cheat

  16. Post processing • What can we do? • Crop photo • Adjust brightness, contrast and gamma • Enhance color • Remove apparent noise speckles • Adjust illumination • Things you can imaging

  17. Post processing example 1

  18. Post processing example 2

  19. Post processing example 3 • Brightness/contrast adjustment • Background blur

  20. My suggestions • Use a tripod if possible • Select lower ISO if possible • If you want accurate color, adjust white balance before picture taking • Use manual mode (“M”) instead of “Auto” mode • Use auto focus • Process your photo before distribute • Practice makes perfection
