Spiked Aurora - Northern Lights near Bláfjöll, Iceland
One of the most interesting feature of shooting Aurora is the ever changing and almost random pattern they form. Usually they form some kind of an arch over the sky. The shape of it depends on how high it is in the sky. If it is near the horizon the arch shape will be clearly visible. The higher up in the sky the Aurora then it looks less like an arch (because you are under it).
This night was different. There was not clear arch shape, the Aurora was everywhere in many forms.
