It stores in the memory the last meter reading that you made in the ambient mode and in the flash mode it will remember several readings and give you a cumulative total of them the I.S.O set, and any other settings even after it has switched itself off, it will not take several individual ambient light exposure readings and average them for that you need the Gossen Starlite. http://www.amazon.com/Gossen-GO-4045.../dp/B00009R944
I've had one of these meters for a couple of years and find it very user friendly, pocketable,robust and accurate, I particularly like the ability to take contrast readings, I do have other more sophisticated digital meters, but this is the one I use most. I hope you enjoy it as much as I do.
