Re: do i need rotating polarizers on my lamps????

You might consider buying polarizing *** material from someone like

http://www.3dlens.com/

Then you can make your own rotating filters. About $10 for an A4 sized
***; they also have adhesive backed film that could be put on a ***
of glass or plastic.

It won't matter how far the filters are from the lamps; what matters is
how much of the illumination on the painting is polarized. If the
plastic filters are too close to the lamps they'll burn.

From an optics standpoint, linearly polarizing the light from the lamps
makes good sense in decreasing surface gloss effects from oil
paintings. The polarization angles will depend on where the lamps are
with respect to the camera's optic axis and the orientation of the
brush strokes.
