Thanks Elsa. This was directly south of Brandberg, on the "road" to the Messum Crater.
Bjorn, thanks for the comment. I basically agree, but the type of editing required is beyond my current skil level. The problem is that with the light level present in this type of shot, firstly the lens is wide open and thus the plant is not in focus, which becomes obvious as you brighten it, and secondly the ISO was very high, thus noise robs even more detail.
I have heard of a stacking technique that can help, but have not managed it yet.
