Close looking over her shoulder of this little girl while she was fetching water for mother, from young they are being thought to do the household and to serve.
Taken in the center of Madurai, in the morning, afternoon all the supplied daily water to containers in town is already gone.
Indeed 1600, the handicap of this tool, you don't see ISO or you have to check, maybe a policy of Canon to show how good they are even in high ISO as the 5D still has not this facility in the ocular unless while you change it, so maybe a choice to chose from a program will be there in the future ?
Advantage of this high ISO: It gives you a wider DOF in low light situations but the exposure must be on top, the underexposed parts gets a lot of grain, so never underexpose in these situations.
PS only undoing grains slightly locally on the lower part of the body, her face and the rest of the shot untouched.
