Some modern LCD monitors are much too bright for photo editing when
set at the factory default settings (which is frequently full 100%
bright). But the instructions for Sypder2PRO tell us to set the
monitor to the default settings before calibrating.

Unless I'm missing something (very likely) I see only two approaches
of calibrating such an overly bright monitor:

1) Ignore the instruction to use the factory default full-bright
setting, and set the brightness to a more appropriate level before
calibrating.

2) Leave the factory default full-bright setting, and during
calibration bring down the individual RGB levels significantly to not
only set the color temperature, but also to reduce the brightness to
an approprate level.

What are the advantages and disadvantages of these two approaches, or
is there a still better way that I've missed?
