summary Documentation of rock art is generally made by drawing with a marker over a plastic film overlaid to the wall of the canyon or cave where it is found. Taking out the drawing printed in the film from the wall implies in loosing important data about its contour because the image became rectified; information about the relief of the documented figure are lost as well. We have used close range photogrammetry methodology to overcome this problem and, on the other hand, to preserve information about the relief of the picture itself, taking into account the fragility of the rock support.
