A footprint is classified as an impression because it has depth (three-dimensional character) in material space (Gaensslen & Larsen 2013: 213). "A positive impression is identical to the object that made it, whereas a negative impression is its mirror image. The shoe prints left in the mud are negative impressions; they are negatives of the shoes' soles. In this scenario, the positives would be the shoes' soles" (Gaensslen & Larsen 2013: 214). In this instance, the impression of the shoe is photographed as a method of preserving the impression: there is a measuring...
