Lesson Goal: This lesson concentrates your attention on the cameras exposure control systems and requires you to be able to apply the knowledge you gain to the labs in other lessons. You will get a background in shutters and diaphragms. You will learn how they work, what goes wrong, why it goes wrong and how to troubleshoot and repair them. It’s also about feedback. How does the computer ‘know’ the position of the shutter and diaphragm, what’s the logic? You also learn about error codes, those distress signals the computer sends out when things go wrong.

When you complete this lesson, you should be able to understand how exposure control works, how to troubleshoot these systems and be able to apply the information when repairing cameras.
