2. Recap
The exposure is the amount of light received by
the film or sensor and is determined by how wide
you open the lens diaphragm (aperture) and by
how long you keep the film or sensor exposed
(shutter speed). The effect an exposure has depends
on the sensitivity of the film or sensor.
4. Correct Exposure
• Balance of light and dark
• Auto mode can generate
• 6 or more combinations
• Subject independent
5. Creative Exposure
• Freeze action
• Show action
• Paint a picture
• Pan or zoom
• Make it rain
by SCholewiak
Right combination of aperture, shutter speed and ISO
6. Focus on Shutter Speed
Using shutter speed to get creative exposures
7. What is the Shutter?
Typically two curtains that open and close to let in light
8. Purpose of Shutter
by unclebumpy
Control the amount of light reaching
the film or image sensor.
9. Amount of Light
by jurvetson
The longer the shutter is open the more light
10. Lower is Faster
• Often displays as whole numbers 60,125, 250, 500
• Represents fractions of time 1/60 second
• 1/2 as much light between stops (1/125 to 1/250)
• Bulb setting
• Control in shutter priority mode and manual
11. Hard to hold
by Tor Håkon
1/(lens mm) typical slowest shutter speed (Hand held)
12. Long Shutter
by F 5.6
A good pair of legs and head
15. Putting it together
by Mykl Roventine
How do I use shutter speed to my advantage?
16. Creative Shutter Speed
• Freezing action
• Slow it down
• Panning
• Zooming
• Making rain
• Painting
Just some of the possibilities...
17. Freezing Action
by SportShotChris
1/500 to 1/1000 second and beyond
18. Slow it Down
• Imply motion
• Tripod or good support
• Moving subject
• Experiment with shutter speed
• 1/2 second to cotton candy
• 8 seconds for tail lights
19. Panning
• 1/30 - 1/4 of a second
• Move with subject
• Smooth motion
• Background critical
• Takes practice by yorkshiregeek
20. Zooming
• Zoom while taking a shot
• Tripod can be helpful
• Start wide and zoom
• Smooth motion
• 1/2 second or more
by roger g1
• Takes practice
21. Making Rain
• A sprinkler
• A subject (flowers, fruit, etc)
• A long lens
• Face the sun
• 1/60 of a second
22. Painting
• 1/4 -1/2 second
• Press the shutter and move
• Left to right or round and round
• Need the right subject
• Abstract and fun by kevindooley
