I got a polarized filter for Christmas. For those who may not know what a polarized filter is or what it does, here are some examples.
There are many uses for polarized filters. Here are two:
1. Bring out the contrast between the sky and clouds
The first picture was taken without the filter. The second and third were taken with the filter, but with it rotated 90 degrees.
2. Reduce reflections or glare on glass, water, or anything wet or shiny. This is the reason many sunglasses are polarized. Note the reflections in the window. Both of the following pictures are with the filter, but with it rotated 90 degrees.
The only editing I did on these ones was scaling so they fit in this space. No colour adjustments.
