Hi Peter
The most obvious concern with this set-up is how you are going to
maintain brightness as the fluorescent tubse in the monitors loses
brightness over time? What setting do you intend to have the monitor
luminosity at for this set-up? It sounds like you are going to turn
the brightness all the way up. If this is a case, the tube will age
faster and probably within a year it won't be able to hit the same max
luminosity. Then you won't be able to hit 120-140 cdm2 anymore, unless
you remove your filter. If you are NOT going to have the brightness
turned all the way up, why do you need to reduce monitor brightness
with a filter? Apple monitors clearly don't have a very precise method
for setting brightness, but isn't there a way to set it and "lock" it
so it can't be changed accidentally by the user?
And yes, if you do go with the ND filter you would have to profile
through it as well.
