Re: [Leica] Incidence Light Measurements

You are definitely right Martin:

For a "bunch of people" the only solution is the gray card or average
reading. But that is only a compromise and one that cannot be circumvented
in that situation. Think of it this way: A very light skinned person is one
stop or more lighter than 18%. Conversely, a dark skinned person such as
Native American or African American is one stop or so darker than 18%.
Tha gray card or 18% reading is the "happy medium" before fine tuning and
not the ultimate authority, especially not in all situations.
The portrait photographer does not expose by 18% readings. At least not the
accomplished portrait photographer.

Some people are going to have skin which appears lighter and some are going
to have skin that appears darker than the grey card.  Why shouldn't the
exposure be the same for all of these!?  <<<<
