We much prefer sheets of tinted Plexiglas hung from two hooks at the
top of the window.  Films applied to directly to windows can damage
old glass, and can be difficult to handle.

The sheets come in a range of filtration and two colors, bronze and
gray. (In most cases we pick the warmer bronze color).  Because
there's plenty of air circulating, there are no problems with
condensation, the windows can be cleaned, and the sheets can be
removed easily.  We recommend that several different filtration
levels be tested before making decision about which ones people
prefer.  The high levels of filtration usually look fine.  Reducing
glare from sunny windows also makes the art easier to look at.
