Taking better aura pictures

People, animals, vehicles and metal structures (including part metal structures like steel reinforced concrete) produce auras as does a lot of sky, so keep these things out of your pictures as much as possible. The tunnel effect in the picture is a reflection of the inside of the lens, it can usually be removed by increasing the focal length (the 18-55 range on Canon kit lenses). Set the focal length below maximum if you can to avoid problems with auto-focussing.
