Gel window to diffuse light

[Michael Waite]

I'm hoping for some advice or recommendations on a suitable gel or other material. I'm exhibiting some work in a gallery that has windows that allow direct sun. Over the course of the afternoon there are different light and shadow patterns moving over the walls and this will sometimes make viewing the work difficult. I don't think the gallery is interested in a long term solution for this, so I want to execute a reasonably priced short term (one month) fix. There are 6 window panes, each about 1 x .5 meter. Perhaps I could just buy sheets of tracing paper, cut them to window size & then position over each pane with some of those new sticky dot adhesives. I was also pondering something like ND or diffusion gels, but haven't had any experience with them. Just wanted to put this out for any ideas or suggestions.

Depends on how dense you want the diffusion, but 216 would work, if you want a bright white look Tough Rolux.
