OMG. that is an awesome link.
i can't beleive those filters cost so much.

. I guess i'm stuck to wait until dawn to get the affect i want for a while.

i found a cheaper alternative - i already have a HOYA pro slimline CPL... stack onto this a quality linear polariser LPL (usually cheaper because they are not suitable for digital) and presto, when you rotate just the linear (make sure the CPL is between the LPL and the lens, and your digital shots will be fine) it darkens exactly the same way as a singh-ray setup
i read somewhere that 2 CPLs stacked together do not produce the same effect. 2 LPLs do, however again with no CPL in the stack, it is only suitable for film shooting
