Reducing light levels

A colleague is seeking help with reducing light levels for a
photographic exhibit. The exhibit will be up for three months this
summer. The light levels is the exhibition space are very high due
to 8 meter high windows. The artist, who is still alive, wants the
view of the Rhine below to be unobstructed as it relates to her
work. The building is listed so nothing can be mounted to the
outside of the building that would change it in any way. The works
are large format so placing individual curtains over them is
impractical. The windows already have UV filtering film, so the
concern is the overall light level, not the UV level which has been
addressed. We are seeking advice on possible solutions to lower the
overall light level in the exhibition space that are quick,
reversible and cost effective.
