This is an interesting post , from an anthropoligical viewpoint , Klondike.
It is quite possible that this is the Mandango tribe of the lower Andes Valley - - - whom are known for their extreme hostility to foreigners .
Example - the taking of a " photograph " , or " picture " is thought to be capturing the ' essence of the soul " , or - capturing the spirit inside the confines of the camera ...
Thus , in most cases , strange camera people are set upon by the women of the tribe , and beaten with large sticks - - - either that , or the warriors of the tribe ( shown armed with the ritual large blow dart gun ) will blow a poisonous dart into the buttocks of said photographer , at which time he will die a slow and painful death - - - unless he ( or she ) is able to make their way back to safety , and the poison is able to be sucked out by one of their compatriots .
I am only pre - supposing that this is the case , and the photographer was able to make their way back to safety , and thus , we are able to enjoy this rare and wondrous glimpse into the fascinating lifestyle of the Mandangoes ......
