7-36. Polarizing  screens  are  being  used over copy lights. Approximately how much of an increase in exposure is required as   compared to using the  lights  unscreened? 1. 5  times 7-41. You have copied a number of slides 2. 2  times and all of the processed images on 3. 12   times the roll are extremely yellow. 4. 20   times What  action   should  you  take  first? 7-37. You are using an ISO 100 speed film to make copies. Your  exposure meter reading is taken from an 18-percent gray card. What ISO speed should you set into the meter? 1. 25 2. 50 3. 100 4. 200 7-38. You  are  producing  copies  using a 14-inch bellows extension. The lens focal length is 6 inches and the indicated exposure is 3  seconds. What exposure time, in  seconds,   should you use? 1. 6 2. 12 3. 16 4. 32 7-39. When photographing images of a CRT, you must be aware of which of the following   requirements? 1. The  shutter  speed  is  extremely critical  when  photographing radarscopes 2. The  screen  brightness  must be adjusted to maximum so the brightest  possible  images  are provided 3. To shoot a computer monitor, you must set the camera shutter speed to 1/250 second 4. The optical axis of the lens must be centered and perpendicular  to  the  monitor 7-40.

By viewing a color slide through a CC10R filter,   you  determined  that the color looks correct. Which of the  following  adjustments  should you make to your filter pack? 1. Subtract CC10R only 2. Subtract CC10M and CC10Y 3. Add CC10C only 4. Subtract CC10C only Learning Objective: Identify proper mixing and storage procedures  for  photographic chemicals. Learning Objective: Identify methods used to duplicate slides. 52
