Have you ever seen a purple cow?
Neither have I! But just a bit of playing in Picasa and I had one.
There is a herd of cattle at the top of our hill. I'll sometimes take shots of them, especially if I can catch some cute ones of the calves.
But on our last walk by, this dopey girl caught my attention!
Here she is in black & white, plus soft focus.
Then for a laugh... focal zoom.
I'll be using this effect for some other projects. I really like it. It's called polarize.
This is the 'pencil sketch' effect. Interesting what it did with the tree background.

And finally... inverted color.
