Effects of using a polarising filter on your Koi pond photos

In one of my earlier post this year, I wrote about photographing your Koi.

If you are using a camera that allows you to fit a filter to your lens, a polarising filter is recommended. Unfortunately, almost all point-and-shoot cameras do not have such capability. For DSLR or SLR camera users, a circular polariser (PL-CIR filter) would do the job. The polariser filter comes with 2 pieces of glass, one fixed and one movable. Once you have decided on your camera angle to take your picture, you need to adjust the movable piece to reduce the glare from the water surface.

Here are the effects of using a polariser filter.  Both pictures were taken using a Nikon DSLR fitted with a PL-Circular polariser. The picture on the right was taken after adjusting the polariser filter to cut out the reflection from the water surface.
