That is the histrogram fooling you, with a dark background and very small
human faces, you should only read the face value, the histrogram will show
nothing because the area of the faces added together is just too tiny
compare with the whole scence. I never read histrogram for stage shoots, I
will only use highlight warning tool if necessary. But in most cases I just
under the exposure by 1 stop to avoid over expose of object, it is any old
rule written on the exposure manual "for stage shoots, set -1.5EV under
exposure".
If you read the face in PS, either RGB value is over 220 then it is not
right to me, I won't care about the background, the object is the people. As
I mentioned before, if it is necessary just use a seperate layer to light up
the background, it is never a good idea to over expose the face even there
is RAW headroom.
