Do you mean masking out a moving person in all bracketed shots except
one, so that Photomatix takes only the information of that one shot
for the person? This may work OK with the exposure blending
functions (which is what I recommended Roger to try), but will require
some handling in Photomatix if you want to create an HDR image from
the retouched bracketed shots.
However, the main issue is when the zone of movements requires more
than one exposure to be exposed correctly (rather likely for an HDR
scene) as the information from just one shot for the zone will then be
insufficient.
