Buffaloes (Syncerus caffer) need to go to water at least once in every 24 hours and will consume up to 35 litres during a single drinking session of between five to seven minutes. Rarely, one might observe a buffalo wallowing in water and when you do, it will be a dominant male most likely to do so, and that will involve a lot of digging and mud tossing in the mud beside the water rather than in the water. This was a challenging capture from an exposure perspective.

A-Z of Photography
Shutter devices in the camera, which determine the amount of light that may fall on film or sensor in a specific instant of time are probably the single most important control in the photographer’s toolkit. Their variable speed, and association with lens aperture, offer many creative options and allow photography in several unique circumstances. Shutter speeds, ranging from fully open to 1/4,000 second in some modern cameras, regulate image output and effect. Camera shutters come in two varieties, a leaf shutter and a focal plane shutter.
“A photographer’s eye is perpetually evaluating. A photographer can bring coincidence of line simply by moving his head a fraction of a millimetre. He can modify perspectives by a slight bending of the knees. By placing the camera closer to or farther from the subject, he draws a detail. But he composes a picture in very nearly the same amount of time it takes to click the shutter, at the speed of a reflex action”
– Henri Cartier-Bresson
