Yashica-Mat EM Light Meter - How to use it

Quick tour of the Yashica-Mat EM light meter
The Yashica-Mat EM sports an uncoupled selenium light meter that requires no battery. If you have one of these cameras, your light meter may still work!
Check your Yashica-Mat light meter against a known accurate one before serious use -- there's no guarantee that these meters are accurate almost 60 years after production.

Thanks. I knew there was a way to move the green arrow but didn't notice the little dial on the side.
