I've gotten some good guesses on the test picture. Thanks for your answers!
To explain what the picture is, I have to explain another thing. We just bought a new camera. After about 5 years, thousands of pictures, and...don't tell Brent...a couple of good falls, my camera decided to stop reliably focusing on things. Sometimes the pictures would come out great and sometimes they would look like you needed to put your glasses on. So, out with the old and in with the new.
Disneyland was the first place we took our new camera, so I took a lot of experimental pictures. (I really do try to read the book, but I'm better at just figuring it out myself.) So, many of you may know that I love Christmas lights. They're one of my favorite things about Christmas. When we were in Frontierland and they had Halloween lights, I got excited to try out my new camera on the Halloween lights. I learned two things. 1) I still need to use a tripod if I'm going to try to take pictures of lights and 2) I needed to turn up the shutter sound on the camera. I thought it had taken the picture so I moved the camera to look at it and as it was moving, it took the picture.
Long story short...or longer, whatever...
The picture is of Halloween lights - hence the orange color - while moving.
Have a great day! :)
