Sometimes accidents are better then the intended photo. I have seen some interesting photos by intention and some by accident on this thread.
I recently wanted to photograph the bunch of cameras I own and use. As it turned out the photos ended up being boring and drab. Kind of like the weather on that day, which was the reason why I was indoors with an itchy trigger finger in the first place.
Here is the boring original.

What saved the day however was an unintentional photo I made before switching to manual exposure and 1/200th of a second. Here is what the scene looked like with a 5 second exposure, handheld

So although not OoF, the motion blur and long exposure with a mix of flash and tungsten gave me an image I like to use as background for my Flickr page
