if you don't meter and just shoot away at base ISO regardless of the lighting, then you won't really know how much noise you'll get in the final image when increasing the brightness afterwards.

If exposure the maximum possible exposure is used the image is as low noise as it can be? But I still do do use a handheld meter to know how much I'm underexposing for the midtone-to-be.

The ISO is the cameras noise/exposure meter, so to speak.

The amount of underexposure at maximum ISO before the point where raising ISO further stops decreasing noise in shadows is my indicator.
