Finally got a chance to play with the new CP filter. I've included a rather boring mud puddle picture that does a good job of showing what the filter can do.
What I didn't know was that besides getting rid of reflections they can also increase reflections! This would work real good for enhancing a reflected sunset or making a rainbow more pronounced. As a side note a CP filter also acts like a 2 stop ND filter, two birds with one stone!
Looking forward to when the Salmon are running in the local rivers, should make for some interesting pictures!
