[en] 3D movies are calibrated to meet a certain screen bright-
ness standard. Therefore, what would be the consequences on
the quality of the 3D experience for spectators watching a 3D
movie when movie theaters do not respect this standard?
First, we attempted to better understand which factors were
important for a spectator by conducting an experiment where
participants watched a 3D movie and filled out an exploratory
questionnaire. Then, we aimed to investigate the link between
image brightness loss and the quality of the 3D experience as
perceived by the spectator. First results show no perceived
difference in the quality of the 3D experience between a nor-
mal brightness and a brightness decreased by 10% for four
factors, i.e. (1) the appreciation of the movie, (2) the con-
tent of the movie, (3) the 3D quality of the movie, and (4) the
quality of the 3D experience in general.
