I was shooting a landscape across a body of water one time and I had a Circular Polarizing Filter on my lens. Since it was bright out, I was still wearing my sunglasses.An interesting bit of information. Did you know that it is easy to convert light into dark?
By the simple method of stacking two polarising filters, rotating one of the filters varies the amount of light that is converted. try it at home folks!
Looking through the viewfinder, I rotated the filter to elimintae the glare of the water and expose the colorful gravel and all of a sudden, the view went dark!
Of course, my polarized sunglasses reacted with the filter, but I'll admit it was a bit of a shock at first.
