These two lionesses (Panthera leo) seem to be most content with their lot, but it is not too clear whether they have eaten or not. Their jowls are remarkably clean, if they have fed. Other lions are still feeding on the other side of the carcass, while the rest of the pride is spread about the kill area. It would seem that these two are merely guarding the kill, perhaps against potential scavengers, the only evidence of which was encroaching Marabou Storks, gathering like undertakers a little distance off.

The World of Lenses
Achromatic lenses are designed to address a problem familiar to both photographer and, believe it or not, astronomers, in telescopes. Chromatic aberration occurs when different colours focus at different distances from the lens, resulting in a soft image, often with colour fringing at high contrast edges in the image. The achromatic lens attempts to eliminate this by bringing two wavelengths (usually red and blue) into focus on the same plane. Lens manufacturers often combine refractive and diffractive optics in a lens to reduce chromatic aberration.
“Landscape photography is the supreme test of the photographer – and often the supreme disappointment.”
– Ansel Adams
