  1. Introduction To EngineeringCamera Lab #1 - 1

  2. What We’ll Do Today: • Receive team assignments • Take some photos with the camera for use in Labs 2 and 3. • We’ll use these photos later to estimate: • Shutter speed • Flash duration • Focal length of the lens • Depth of field of the lens

  3. Lab 1 Goals • To introduce engineering and design through the study of one-time-use camera. • You will take photos with camera of: • Spokes of moving bicycle (with and without flash) for Lab 2 • Each other • Array of meter bars for Lab 3 • Introduce idea of estimating camera performance characteristics (parameters) • Introduce concept of measurement error

  4. Procedure • Find your lab table. Introduce yourself to the other members of your group • Each group will go to each of the three stations: Shutter, Flash, and Focal Length. • Be sure to take photos at each of the three station.

  5. Shutter and Flash Speed Estimation • Take photos of bike wheels (when the bike is being pedaled at 15mph) • Without using the flash (use flood lights on the wheel, and cover the flash window) • With the flash • Measure outside diameter of bike wheel • Knowing the wheel angular speed, we can use the results to estimate the shutter speed and flash duration

  6. Depth of Field and Focal Length • Take photos of meter bars at known locations. • The photos and negatives of the meter bars will be used in Lab Session 3 • Lab 3 deals with optical measurements (focal length and depth of field). Be sure to bring both photos and negatives for meter array to Lab 3.

  7. Film Processing • After lab, shoot the remaining film on the roll, then have it developed. Wherever you take the camera, be sure to ask for the camera back when they take the film out. • Bring the photos and camera with you to class next week.

  8. Summary of Procedure for Today • Find your name at one of the tables, and introduce yourself to your group; • Each group will rotate among the two bikes and the meter bars. • Make sure you get photos of your lab group, both bikes, and the meter bars • Be sure to get the camera back when you have the film processed,

  9. Words of Warning • Bring the camera and photos of bike wheels with you to the next lab session. At that lab we’ll take the camera apart. • Do not take the camera apart yourself ahead of time! It contains a capacitor charged with 330 volts, and it can give you a nasty shock if you touch it!
