Thanks Paul.
These filters are pretty steep in price and I was wondering if we can achieve the same effects in post using PS.
A lot depends on whether you want to spend time in back of a camera or in front of a computer.
You might be able to duplicate the "color intensification" in PS, although not the glare/reflection-cutting function of a polarizer. My poor man's version of "color intensification" is a slight tweak of RGB saturation combined with subtle mid-tone contrast adjustment. It's not quite the same but works for me.
