I hadn't really done a lot of work with this filter before, so I took some time and played around a bit.
This is the photo I started with:
I then followed the directions in Lesson 2, which gave me this:
I understand that some people are fascinated with black and white photography. I am not one of them. Therefore, I wanted to get some color back into the picture. Because I always try to remember to save my selections as alpha channels, I was able to pull up the cliff (in channel 4) as a selection (Ctrl-Alt-4), invert the selection (Ctrl-Shift-I) and delete. This provided the following, which makes it somewhat unclear whether we're looking at a cliff or a waterfall. I like ambiguity; it makes me think.
OK, sez I, what about using this effect on other things. Here we have a perfectly good red-tailed hawk with a totally boring sky.
After selecting the sky, expanding the selection by two pixels, and applying the Plastic Wrap filter; then applying a Radial Blur (28 px, Zoom, Good) and Blend Mode Overlay, we get this. Somewhat less boring, I think.
