many, but depends on photographer's choice of file upload (newer event = more likely to work) and your device's capabilities. You may experience slow playback, distorted images or unexpected browser quitting if there is only limited memory/GPU power available.
Meat vendors hawk their wares in the main market of Oaxaca, Mexico. The smell of barbecuing meat permeates the air and shafts of sunlight streak down through the haze of a dozen smouldering coal fires. Tides of people shift this way and that, and vendors whistle and call, trying to attract the attention of passerbys. It's a white balance dream: the ceiling is painted blue, illuminated by cool sunlight, while the red of the meat is accentuated by the warm glow of incandescent lights.
Captured during a rare lull in the crushing crowd, the shot was immediately followed by a gaggle of Nikon shooters coming through, bright camera straps and shiny lenses glinting conspicuously in the dappled light.
The small round sausages are chorizo, and lunch next to the Coca Cola fridge will set you back about 30 pesos.
