  1. Making Better Pictures A presentation to Area 2 CAT, November 19, 2009 By Derek Southern, Branch 8

  2. Photographyis “Painting with Light”

  3. How much Light? We have two ways to control how much light enters the camera: • Shutter speed • Aperture But we can also control the sensitivity of the sensor inside the camera using ISO settings from 50 – 3200+

  4. Shutter speeds Fast Slow

  5. Apertures Wide open Closed down Fast lens $$$ Slow lens

  6. Equivalent exposures

  7. How much Light is enough?

  13. Histograms tell all!

  14. Is this a well exposed picture?

  16. AVOID the 3B’s of Poor Pictures • Blurry • Bad • Boring

  17. The 3B’s of Poor Pictures • Blurry • Bad • Boring

  18. Better? Focus on main subject, then recompose, and finish the ‘click’ 

  19. The 3B’s of Poor Pictures • Blurry • Bad • Boring 0.6 secs, f/5, ISO 400, auto-exposure

  20. Any improvement? 1/10 sec, f/6.3, ISO 400, exposure set manually

  21. Some Ways to Reduce Blur • Use a tripod

  22. Some Ways to Reduce Blur • Use a faster shutter speed (lens speed becomes an issue!) by selecting ‘action’ or ‘sports’ option

  23. Some Ways to Reduce Blur • Remember shutter button has a two stage action; pause at mid-point, then press slowly without jerking camera. This allows autofocus to happen in the background. Then recompose picture if needed. Remember this one?

  24. Some Ways to Reduce Blur • Use ‘Image Stabilization’ (Canon’s term) to be able to hand hold camera at slower speed

  25. Some Ways to Reduce Blur • Rule of thumb with zoom: minimum shutter speed = 1/focal length of lens e.g., With a 200 mm lens use 1/200 sec shutter speed or faster

  26. Some ways to reduce Blur • Use a tripod • Use a faster shutter speed (lens speed becomes an issue!) by selecting ‘action’ or ‘sports’ option • Remember shutter button has a two stage action; pause at mid-point, then press slowly without jerking camera. This allows autofocus to happen in the background. Then re-compose picture if needed. • Use ‘Image Stabilization’ (Canon’s term) to be able to hand hold camera at slower speed • Rule of thumb with zoom: minimum speed = 1/focal length of lens

  27. Canon SD450

  28. Use the Camera Mode Functions • Use faster shutter speeds to ‘stop’ action or reduce blur caused by camera shake: set ‘Action’ mode • Use SMALL aperture (larger number like f/11) to increase area of sharpness : set ‘Landscape’ mode • Use ‘Macro’ mode for close-ups (stamps, shells, flowers, ornaments, things to sell on eBay, etc) • Use ‘Portrait’ mode and with the LARGE aperture (small number like f/2.8) you have a reduced Depth of Field and get a blurred background

  29. Select an appropriate mode selector

  30. Better pictures of children • Get down to their level • Use natural light, if possible: (avoid flash!) • Zoom in; fill the frame • Save highest quality pictures(you will need more memory cards, they are cheap and memories are priceless!) • Pre-focus by pressing shutter release half way. This also reduces shutter lag time – if you don’t do this the action has happened by the time the camera takes the picture!

  31. Pictures of Children 1/80, f/2.8, ISO 400

  32. Pictures of Children 1/100, f/2.8, ISO 400

  33. Newborn: zoom and flash The hospital room was not well lit. I moved away from mother and child, used zoom to fill the frame, and added flash 1/60, f/5, ISO 400, 200mm, flash

  34. Improving our pictures:The ‘Rule of Thirds’ • Imagine a “Tic-Tac-Toe” 3x3 matrix superimposed on your picture (some cameras offer this feature) • Avoid having the horizon in center of image • Avoid having person/subject right in the center • Have space in the direction a person is looking • BUT - Break the rules when you need to!

  35. Better composition • The ‘Rule of Thirds’

  36. Using grid

  37. Make a picture!Usepanorama when you need to

  38. Avoid Flash! Unless you can’t!!

  39. No Flash!

  40. Flash is Short Range 1/60, f/2.8, ISO 400, with flash

  41. No Flash, but manual control 1/6, f/2.8, ISO 1600, NO flash

  42. Other ways to improve Pictures • Fill the screen- zoom, or get closer • Change your view point • Use scenery to ‘frame’ your picture • Do NOT use digital zoom! • Bracket the exposure • Change the White Balance • Take multiple shots(especially if this is an important picture)

  43. FILL the screen

  44. MOVE ? - First viewpoint

  45. MOVE? - Second viewpoint

  46. Not a good day for photography

  47. Better Day – Different View

  48. Fill screen and frame

  49. Another way to frame a picture
