Lesson 6 / Camera Metering Circuits

AI (artificial intelligence) Light meters systems have been the unsung advancement in digital cameras. This lesson starts you at the beginning but in one page we advance you to the start of modern metering, the photodiode (SPD) coupled with Op Amps. You will recognize this metering system from your lab in Lesson 3. We take you through the gauntlet of encoders, calculations, A/D converters and troubleshooting all the way to current Matrix metering systems. 

When you complete this lesson you should understand light meter systems, how calculations are done and how to troubleshoot and repair metering systems.
