When and How to use a Polarizer Filter

There are very few situations in wildlife photography that call for the use of a polarizer filter. I am not a proponent of using software to apply filtering effects after the image has been taken. I prefer to do it right in the first place and use a thin Hoya and B&W circular polarizer for my travel and landscape photography needs. You can see my works on MichaelDanielHo.com
