Kudu (Tragelaphus strepsiceros), one of the most graceful large antelopes in the Mana Pools area, pauses in the shade of a mahogany tree. This animal often relies on crypsis (a synonym for animal camouflage and anti-predator behaviour, such as stillness) allowing close approach by the threat. Once in flight, those magnificent horns are tucked along the back of the antelope through head held high.

Lighting ratio is a measure of the difference between key light and fill light. Key light is the main source of light which casts shadows versus fill light which is the light that fills in the shadow areas. The higher the lighting ratio, the greater the contrast. Although this may be manipulate with f-stop adjustment, a more effective or practical adjustment can be achieved in post photo processing.
“When I was just starting out, I met Cartier-Bresson. He told me it was necessary to trust my instincts, be inside my work, and set aside my ego. In the end, my photography turned out very different to his, but I believe we were coming from the same place.”
– Sebastiao Salgado
