Yesterday we had a kids Halloween party in the afternoon, then had one for the adults at night. I had been taking pictures through the night and every single one of them was clear. No dust, clean lense, ect. Then, out of all of them came this one:

The picture before and the picture (all taken within mere minutes of eachother) are clear as a bell. It's a digital, Kodak easyshare, nothing fancy. I've had other things like this happen when this same group gets together. I'm just starting to learn about the whole catching things on film bit. Usually I just see it and go "oh, okay" and that's it. But I'm getting a lot more interested in it as seems it seems to be happening more and more in my pictures lately.
Thoughts?
