Do this: put your camera in spot meter, point it at the brightest thing in the frame you want to keep, set your SS and/or aperture so that the meter reads 2 stops over center (to the left), then lock the exposure. Auto-ISO will set the ISO at whatever it needs to, based upon your chosen SS and aperture. If ISO is already at it's lowest point and you're still over-exposed, just add some shutter speed before you lock it.

I have a Nikon D7000 and with Auto ISO set you do not get the lines as ISO adjusts things to keep metering on center at least till you reach setting limits.

This does work with b3, Easy Exposure, turned on(auto reset) in A,S,P but not in M. It will adjust EC and you will see the lines and then reset it when done.
Those two lines = .7 EC.

Simple and easy.

Actually, let me re-phrase.

When you're spot-metering, you set the exposure so that you get the lowest ISO possible, but still maintain the SS and aperture that you need. So, you could just apply -2 EC. Make more sense?

This works, which we've previously established but you do have to reset EC when done but is easier/quicker then dealing with going to fixed ISO.
