Poisonous Food


The tip of a branch of the Lesser candelabra tree (Euphorbia cooperi) or its variant calidicola just coming into bloom. This plant occurs throughout the Zambezi Valley in wooded areas, in fact calidicola is exclusive to the Valley. It’s a toxic plant (containing rotonin), with a milky latex that is both pungent and acrid to the smell, causing serious irritation to skin exposed to the latex and even a burning sensation from its fumes if inhaled. The latex may cause blindness. The substance is known to have been used for fishing (it denies the fish oxygen and causes paralysis). Yet, it is on record that the candelabra tree is a favourite of the rhinoceros, which once roamed the Zambezi Valley, but since decimated by poaching. In more arid regions of Namibia the Euphobia is a staple for the rhino’s survival.

A-Z of Photography
Vignetting may be entire intentional (in fact some may use vignetting filters in their compositions) or unintended underexposure on the corners and edges of an image. An unwanted vignetting is usually caused by an inappropriate lens hood or object which partially blocks the field of view. This was a technique used during printing to achieve a full exposure of the central area of the image with fading or darkening edges, and was at one time common with portrait work. The term is derived from the French vignete (diminutive of vigne or vine).

“But also to me, the Holga, the way these images are, that they are sharp in the centre and they vignette in the corners is more how we really see. When you’re looking at the world, you’re not seeing a scene that is sharp all the way to the edges and bright all the way to the edges and has straight lines. You’re seeing something sharp in the centre and then the rest of it is all kind of blurring out.”

Stuck in darkest Africa, lost in the wild and loving it! Don’t let me out of here…

  1. Encountered those and were often the only shade. Do we sit under or not… I have seen birds making holes for nesting and for the life of me now cannot remember what they were.
