I tried looking on your site Greg to see what type of fall this would be called. It really was just a very small portion of a creek. Well, I've been bored and needed to get out, since there's not a whole lot of color around I took time for a few of these...I used the circular polarizer but I'm not sure if I got it right. I would make sure it was on securely but from twisting around-a few times and watching for the slight change, it had came off and I would lose my vision.  ...

Juanita, you really should be able to twist the polarizer freely without it coming off of your lens. It is a two piece filter so the mounting threads are independant from the actual filter element. The first picture looks pretty good, but the second one it appears that you weren't using the polarizer to the fullest. There is still a good deal of glare on the wet rocks which should have been darkened with the filter.
Keep up the practice! This is the best time of year for waterfall photography in my opinion. You will find there are much fewer people around the water when it is cold like this. Plus the ice makes for a geat added element when it gets really cold.

One of my polarizers is a little stiff to Juanita. I have actually been trying to teach myself to turn it the other way. i have tried to rotate it over and over to "loosen" it up like you do a new set of pliers. still no change.
25 seconds seems like a long time letting light into your camera (depending on your available light) even with a EV @ -5 this might be why your blown out over such a large section of the image. 1-2 seconds is all your really need to capture the smooth movement. even with a CPL set correctly you may be letting to much light reach the sensor for to long.

You captured some great colors with these Juanita. People have differing opinions as to how long an exposure works better with what subject. You can probably see that the longer the exposure, the softer the effect as Greg mentions in his tutorial.
Personally, most of my waterfall photos are about 1-1/2 seconds which gets me the effect I prefer. This shutter speed is adequate to get the favored silky effect but is "hard" enough to still look like running water.
I've had the same problem with polarizers. I attach my filters loosely, just until I feel one tighten, for fear of not getting them back off. But with adjustable filters like polarizers, I've had to get in the habit of turning them only one way.
