Because you said, ""Total light on the sensor" is a meaningless concept."

It is, unless you're having a theoretical discussion of sensor noise, which I'm not.

It's useful for much more than that.  I use it all the time in actual shooting conditions because I often shoot with two or three different formats at the same time.

There is no concept of "total light on the film" either.

Yes, there is.  More film = more light captured.  Why do you suppose MF cameras do better in low light than 35mm cameras, or 35mm cameras do better in low light than 110 cameras even when using the same type of film?

Go out and shoot with your "total light" settings if you like. I could care less.

Then why are you here lamely attempting to "diss" that which you don't understand and don't care about?
