Hi, I am going to Banff / Yoho NP in September. I see many great oportunities there to take pictures of mountains reflected in lakes and ponds. I have been reading mixed opinions about using Circular Polarizer filter on reflections. Some say it is necessary while others reason that Polarizers only mess up the shot. I purchased the book on photography in Canadian Rockies by Darwin Wiggett. Almost all reflection pics in the book are taken with Sing-Ray Warming Polarizer Plus. By definition, polarizers REDUCE reflection. What am I missing here?
