Subject: Ask Peter: Polarization

Please pass this email along to Peter Kolonia with thanks for his October article about light polarization, not just because it draws attention to L-S&M, but for publicizing a fairly unfamiliar technique which can be hugely valuable to many photographers. As a writer with the freedom to fill hundreds of pages, I admire anyone who can boil a topic down to a single page!

I just wish he had space, though, to mention the importance of the orientation of the axis of the polarizing filter. For maximum effectiveness, the axis of the polarizer on the lens needs to be perpendicular to the one on the light and, as much as the lighting angle allows, the axis of the polarizer on the light should point toward the camera.
