“PAINTING WITH LIGHT”
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+
SHUTTER SPEEDS
Fast
Slow
APERTURES
Wide open
Closed down
Fast lens $$$
Slow lens
EQUIVALENT EXPOSURES

AVOID THE 3B’S OF POOR PICTURES
• Blurry• Bad• Boring
THE 3B’S OF POOR PICTURES
BlurryBadBoring
BETTER?
Focus on main subject, then recompose, and finish the ‘click’
THE 3B’S OF POOR PICTURES
BlurryBadBoring
0.6 secs, f/5, ISO 400, auto-exposure
ANY IMPROVEMENT?
1/10 sec, f/6.3, ISO 400, exposure set manually
SOME WAYS TO REDUCE BLUR
Use a tripod
SOME WAYS TO REDUCE BLUR
Use a faster shutter speed
(lens speed becomes an issue!)
by selecting ‘action’ or ‘sports’
option
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?
SOME WAYS TO REDUCE BLUR
Use ‘Image Stabilization’
(Canon’s term) to be able to
hand hold camera at slower
speed
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

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 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
SELECT AN APPROPRIATE MODE

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!
PICTURES OF CHILDREN
1/80, f/2.8, ISO 400
PICTURES OF CHILDREN
1/100, f/2.8, ISO 400
NEWBORN: ZOOM AND FLASH
1/60, f/5, ISO 400, 200mm, flash
The hospital room was not well lit.
I moved away from mother and child, used zoom to fill the frame, and added flash
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!
BETTER COMPOSITION• The ‘Rule of Thirds’
USING GRID
MAKE A PICTURE!USE PANORAMA WHEN YOU NEED TO
AVOID FLASH! UNLESS YOU CAN’T!!
NO FLASH!
FLASH IS SHORT RANGE
1/60, f/2.8, ISO 400, with flash
NO FLASH, BUT MANUAL CONTROL
1/6, f/2.8, ISO 1600, NO flash
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)
FILL THE SCREEN
MOVE ? - FIRST VIEWPOINT
MOVE? - SECOND VIEWPOINT
NOT A GOOD DAY FOR PHOTOGRAPHY
BETTER DAY – DIFFERENT VIEW
FILL SCREEN AND FRAME
ANOTHER WAY TO FRAME A PICTURE

LOOK FOR DIFFERENCES!

OUTDOOR PICTURE, RON AT SIRS IN THE KITCHEN: NO FLASH
1/160, f/4.5, ISO 100, no flash
RON WITH “FILL FLASH”
1/80, f/5.6, ISO 100, with flash
OLDEST OBJECT ~2M YRS, IN BM
OLDEST OBJECT IN BM – NO FLASH
MACRO MODE – GET CLOSE
EVEN CLOSER!
