My approach will be filters the same as with some variance of exposure methods: Take more than one shot.  I certainly would take one with the filter(s) and one without..except when using polarizer I generally just leave it on camera for the shoot if appropriate.  Now, my pol. will not fit my fav lenes.  Good thread.  We all benefit from the thoughts of others here.  Tom.

We may have had a thread or two on filters previously (?) but this one I am reading and find it quite intriguing.
