Evening Psych, Wonderful images you captured. I do have a couple of suggestions - not about the images, but about the comment on pairing a polarizer with a wide angle lens. The pair does not mix well - sort of like oil and water. Here is why. Polarizers work well out to about the mid 20's in focal length. Wider than that they are unable to apply their corrections (just plain optics) in a uniform manner across the face of the lens, hence your results will show a very uneven polarization in particular to the sky (which is very noticeable). The polarizing filter applies its greatest correction 90 degrees to the sun, and progressively less as the angle lessens. The sky will show a very deep blue in one area then fading out to the standard sky across the rest of the image. Some folks prefer this, others do not. It really depends on your taste.
You can see that one of the application techniques is to flip the orientation from landscape to portrait, however you still have a significant difference in the sky.
Polarizing filters can be expensive - especially for the larger objective lens. Most wide angle lenses have large objective lenses, along the lines of 70mm+. The filters of this size come at a premium price. Quality filters commend an even higher price. Then with wide angle lenses you have to consider vignetting. To either eliminate or lessen the vignetting potential one usually considers thin or low profile filters, which commands an even higher premium. When you add all of these premiums together, you come up with a pretty nice price point.
So what are we talking about here. I picked up a Nikon (when Nikon was making filters - they left the business several years ago) 77mm low profile, wonderful quality filter and I think it ran $150 for use on my 12-24. I have used it a number of times, but I am careful to not include a lot of sky. I have found that it works on water, a bit differently than on the sky, as the un even application is not as apparent.
The other thing I was going to say, is that the wide angle lenses tend to have more contrast than the normal or telephoto lenses. The render richer, and so they tend to not really need the assistance of a polarizer.
I think you can actually do better through adjusting the images in photoshop, than with filters in the case of wide angle lenses.
