: AI Lightemeters 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.
When you complete this lesson you should understand lightmeter systems, how calculations are done and how to troubleshoot and repair metering systems.
