Exposure, as you know, is UNAFFECTED by ISOspeed. It is only a function of EV (f/, shutter interval) and scene luminance. Output brightness IS affected by ISOspeed (and other image processing variables).

That is not true. If you leave everything untouched, but increase the ISO by two clicks, you will see your EV meter value goes up by +1.0. This is an EV (Exposure Value) and you can see this change on the EV meter. What would you call this?
