We've featured a lot of really neat photos on Neatorama, but I think this one is definitely in the top 10. Here's a photo by Richard Heeks of a soap bubble bursting:
The lighting of this shot is natural - sunlight through cloud. The Nikon D90 is great for giving clear images at high ISO (here ISO 800); making this shot possible.
N.B. This is a real photo of a soap bubble bursting. I've made slight edits to raise colour and light, but this is just to add some punch. This is not a Photoshop creation!
