  1. Camera Basics Day 1- Shutter Speed Day 2- Aperture Day 3- Light meter and Manual Mode Day 4- ISO

  2. What 2 mechanisms allowlight into a camera? Aperture and Shutter Speed

  3. SHUTTER SPEED • Controls the amount of light that is allowed into the camera by the amount of time it is left open • This can effect: • Motion captured • -Lightness or darkness of the photograph

  4. Fast Shutter Speed • 1/250, 1/500, 1/1000 • The faster the shutter speed, the more likely it is that you will be able to “freeze” the subject • ….but also the less light you are letting in Non-moving subject**

  5. Slow Shutter Speed • 1/4, 1/8, 1/16, 1/30 • The slowerthe shutter speed, the more likely it is that your subject will be blurred • ….but also the more light you are letting in

  6. Safest Shutter Speeds • No lower than 1/30-1/45 s • If you must take a picture using a shutter speed of 1/30 or below than you need to use a tripod or set the camera on a flat surface.

  7. Slow Shutter = Blurred Motion 1/60, 1/30, 1/15, 1/8…….

  8. Fast Shutter = Frozen in Time 1/250, 1/500 1/1000, ………..

  9. How to Pan • Set the shutter at about 1/45* • Following the action while you are taking the picture • Release the shutter and continue following the action

  10. B • The “B” on your shutter stands for bulb, this allows the shutter to stay open as long as your finger is on the camera • Used mostly for night photography • Use a tripod if you are using the B

  11. Shutter Speed Control Mode -On the Cannons- TV -On the Fujifilms- S Combat the issue of under exposure with aperture* Where to find it on the camera

  12. Shutter Speed Review • Give me a thumbs (up down or in the middle) if… • You remember what shutter speed is • You remember what type of shutter speed to use if your subject is moving quickly (fast or slow) • You remember what type of shutter speed lets in MORE light (fast or slow) • You remember when you should use a tripod • Bonus: Your remember what the “B” stands for • Challenge: When in AV/ shutter speed control mode, what your camera changes to combat any exposure issues…..

  13. APERTURE • Aperture refers to the opening of a lens's diaphragm through which light passes. • Controls how much light comes into the camera (the intensity of light) • Film Camera Lenses

  14. EYE get it! • Works like an eye • What happens to your pupil when you go in the dark? • Your eye gets larger to let in more light • What happens to your pupil when someone shines a flashlight at it? • It gets smaller, doesn’t let as much light in

  15. Aperture= F-Stop= lens opening • F-stop = Focal length/Aperture diameter • F-stop= F 2.8 – F 22

  16. Fractions in Art? • The f-stop with the LARGEST FRACTION is going to let in the MOST amount of light f/2 f/2.8 f/4 f/5.6 f/8 f/11 f/16 f/22

  17. Fractions in Art? • The f-stop with the LARGEST FRACTION is going to let in the MOST amount of light f/2 f/2.8 f/4 f/5.6 f/8 f/11 f/16 f/22 1/2 is larger than 1/22 f/2 f/22

  18. What does changing the aperture do to the photograph?

  19. Depth of Field The area of your photograph that is in sharp focus, the areas in front of and behind your subject

  20. Large (Great) Depth of Field • The subjectandthe background will be in focus Small Aperture hole – Think about Squinting Large Number – F/16 or F/22

  21. Small (Shallow) Depth of Field • The subjectBUT NOT the background will be in focus Large Aperture Hole – Allowing more light Small Number – F/2.8 – F/4

  22. How do Depth of Field and Aperture Work Together?

  23. Another way to look at Depth of Field

  24. Aperture Control Mode -On the Canons- AV -On the fujifilms- A Combat the issue of under exposure with shutter* Where on the cameras…

  25. Lets go to the commons! F /2.8 F /5.6 F/ 9 F/ 8 F/ 13 F /11

  26. Aperture and Shutter Review • Are the two things that control the amount of light that reaches the film • You need a correct combination of both in order to let in the right amount of light • Shutter speed controls the amount of time light has to enter the camera • Aperture controls the amount of space light has to enter the camera • Lets look at the cannons on MANUAL MODE

  27. Manual Modes • Get in groups around the cameras, no more than 3 people to a camera • Canons first • Now Fujifilms

  28. Videos to Review Aperture and Shutter Speedshutter- http://www.youtube.com/watch?v=gnl55vfUChYaperture - http://www.youtube.com/watch?v=34ReeL-MBXk&list=PLp-znpQge8HxrllwXwn9B0Xxf1f7BQnXC&index=3– depth of field one - http://www.youtube.com/watch?v=l3zdybilbCY&list=TLHI-fhf_0LvE01I3jffSFrG4_FTrHdxZV

  29. How do you know if you have to correct amount of light in your camera????

  30. LIGHT METER • Measures light levels within the area you are photographing

  31. Proper Exposure

  32. Changing the Exposure • To get the proper amount of light (your light meter reading in the middle) you change aperture and shutter speed. • Reciprocal System- Once you know the correct combination of shutter and aperture, you can change one setting as long as you change the other setting to match it- i.e. let in the proper amount of light

  33. For example… f/2 f/2.8 f/4 f/5.6 f/8 f/11 f/16 f/22 1/4 1/3 1/15 1/30 1/60 1/125 1/250 1/500 Faster Slower

  34. ISO • International Standards Organization • It is how sensitive the camera is to light

  35. ISO • The HIGHER the ISO number ( FASTER film) the more sensitive the camera is to light, BUT the grainier the image • The Lower the ISO number the less sensitive the camera is to light, BUT the clearer the image • IDEAL film is 200/400 (less grainy) • But you need good light

  36. If outside and really bright, set it to 100 If outside and cloudy or dim, set to 200-400 If dark or inside, set it to 800 – 1600 There is a CATCH… grainy
