I must admit, like Charles Dodgson, I have a weakness for images that illustrate concepts in mathematics and logic. This image was appropriated for a module on proportions in the United States; namely, the size of the image varies inversely as its distance from the observer (or the camera).
Marina Castillo lives in Mendoza, Argentina and this image is part of a series called ‘Scenes of dwarfs and giants’. One cannot be completely sure, but it does appear that these scenes were constructed conventionally and not digitized. If so, then a special setting or lens would have to have been used to maintain a depth of focus for the subjects in the frame. This one which means “balancing forces” has the additional appeal of being a nod to girl power.
