Anyone know the best alignment for the CPL filter? It rotates (has a slip-ring) and notches, so you can adjust the polarization from horizontal, vertical, 45 degrees etc.
Sunglasses also are polarized to reduce glare. It sounds like vertical polarization is best to reduce glare, which I think is the slip-ring notches at 12 and 6 o'clock.
Look through the CPL filter at any LCD screen (which is a polarized source) and rotate the filter, and you can see clearly to black then back again.
