After about 25 years of being interested in photography I finally understand f-stops; how they relate to shutter speed; and how they both are used in conjunction with an incident light meter. I owe my new found understanding of the f-stop to this excellent web page, and my understanding of incident light meters to this page.

I found a couple incident light meters on eBay and I think I am going to buy one. Maybe this one. I either have to figure out how to sign up for an eBay account or ask Sheri's friend that does a lot of selling on eBay to bid on it for me.

We have been talking about when Sheri gets a new job we might buy this camera. A light meter would be the perfect accompaniment for that.
