Nothing wrong with those el cheapo thin sections!  Nice shoot, Richard.

Another excellent source for Linear Polarized Filters is:

Rainbow Symphony, Inc.
Reseda, Ca 91335
(818) 708-8400
www.rainbowsymphony.com

They manufacture L.P.Filters made like 35mm slides.  Their advantage is
that they can be turned any ole whichway with the filter surfaces not
rubbing against each other and causing scratches, which is never no fun.

Looking forward to your additional posting of more thin section photos.

Yours for crossed polars!
