I have two goals for today! • Demystify digital cameras and their settings • Share ideas for using digital cameras in your classroom
How does your camera “see” the world? Through the lens! • Zoomed out • Zoomed in • Macro?
*Zoomed out* How your camera sees the world Camera can focus from ~1 ft. to infinity
*Zoomed in* How your camera sees the world Camera can focus from ~1 ft. to infinity
*Macro* How your camera sees the world Camera can focus from ~1-12 in.
Activity: How different lenses “see” • Turn off your flash • *In macro mode* Zoom all the way out and frame the toy so you can see the front and the back (fill the frame!) • Back up and zoom all the way in and repeat
Activity: How different lenses “see” • Choose a partner and repeat the exercise, using their face as your subject • One shot zoomed out • One shot zoomed in • Fill the frame!
Three essential parts of the camera Aperture Shutter Sensor (or film)
Measuring Light The Aperture
Measuring Light f/2.8 f/8 f/22 Shutter open 0.1 sec. Shutter open 0.5 sec. Shutter open 1 sec.
Depth of Field The distance in front of and beyond your subject that appears in focus
2 Ways to Control Depth of Field • Aperture(how big the “light pipe” is) • Focal Length(how far you’re zoomed in)
f/22 (1 sec.) f/8 (1/8 sec.) (1/60 sec.) f/2.8
Controlling DOF with Focal Length 115mm lens (i.e. zoomed ~half way in) 560mm lens (i.e. zoomed all the way in)
What do the preset modes do? Math! (among other things)
Preset modes Portrait (Limited Focus) Landscape (Infinite Focus) Fast Shutter (Sharp Action) Slow Shutter (Blurry Action)
Low-light help: ISO (“Film” Speed) *Doubling the ISO cuts the shutter speed in half* ISO: 100 Shutter Spd: 1/2 sec. ISO: 3200 Shutter Spd: 1/64 sec.
One more helper—Flash Illuminates a scene for between 1/2000 and 1/30,000th of a second
Activity: “Panning” and the illusion of speed Trisha is going to scoot across the room. Your job is to take a picture where she appears in sharp focus, yet the background is blurry. Camera SettingsPreset: Try Landscape or Slow ShutterISO: 50 or 100Flash: OFF
Activity: Stopping Motion with Flash Camera Settings and Technique • Choose Auto mode or Fast Shutter • Turn flash ON • Get in close • Keep shooting until you get nice, crisp shots! Pair off - each pair grab one cup and one spoon. Choose a person to fill the cup with water.
Class activity School event Field trip Home A process 1.) Documentary imagery…
Illustrate steps in a procedure • Gather your materials • Cut a holein the top • Scoop outthe insides • Draw aface • Cut outthe eyes… • Then the noseand mouth • Put a candleinside • They don’tlast forever! Images from: http://www.geocities.com/Athens/Olympus/7123/jack.html
Activities for Documentary Photos • Class Activities or Field Trips • Writing prompt • Newsletter • Thank you • Books • Alphabet Book • Rhyming Book • Classification Book (Things that are cold)
2.) Perspective • Where is the camera looking from? • High • Low • From the side
Animal assignment Become an animal
Perspective Power Who’s in charge here?
3.) Changes over time • Short term • Long term • What do you see changing?
Family Aging Samples from: http://zonezero.com/magazine/essays/diegotime/time.html
Same place at different times of day 9 am 9 pm
4.) Motion or Stillness • How can you convey motion? • How can you convey the lack of motion?
Making the strange familiar and the familiar strange

6.) Concepts Things like: • Symmetry • Love • Pain
Concept: Symmetry (Found in Nature)
Concept: Symmetry (Man-made)
