Acacia Rivers. Ngorongor Conservation Area, Tanzania, East Africa

The acacia tree, synonymous with the plains of East Africa, allowing the sky to mimick the flow of some fantastical river through the branches. Its old hat, but photographers will always bang on about looking up.  Certainly worth it on this occasion. On top of that, this was shot on my iphone.  As a result this image is only availalbe in one size: 25cm x 18cm, but framed with a large white mount and a black frame, its effect as a window to the outside is fantastic.
