Subject: Re: Polorizing filters (free ones)
Reagarding where to get polarizing filters;
I called Polaroid last year-- the number is in the back of the Snackbook, I
don't have my copy with me but maybe someone else can post it? They seemed to
only sell huge quantities at huge prices but asked if I would like some
free samples (of course!) and they sent me an envelope full of approx.
10 cm-square filters of different types.
