Mesmerizing, isn't it?
This coral (I think...) is at the Aquarium of the Pacific, which held their Photographers Night this evening. If you live anywhere in Southern California, I highly recommend attending. For about 4 hours, photographers get the run of the place and are allowed to use tripods and flashes.
I like the colors and details on this coral. I ended up going back multiple times to re-shoot it with various settings since I liked it so much.
I will post more photos soon. While you're waiting, feel free to check out my galleries from past events: Photographers Night 2011 Photographers Night 2010
