Plein Air Two Hand View Finder or Painting Mask

My right arm is bent at the elbow at 90 degrees and held firmly while the left moves. The closer the arm is to a straight line the smaller the image is in the box formed by my fingers just like a camera viewfinder. In addition a 21 box grid can be made by spreading the fingers apart and flicking the left wrist to lineup with the left arm.

At the Lima Anthropology Museum there is a diorama display of what anthropologists think Mesoamericans' camps were like around 14,ooo B.C. Most of the activities were self explainable except one man wearing an animal's head disguise. He was facing the wind break enclosure. He appears to be sizing up a distant object. He could be measuring where to put another support pole to add to the enclosure or judging from his posture. He could be roughly gaging the speed of movements of people or animals on the horizon.
