Iain Blake is an amateur photographer that has gained his popularity on the Internet thanks to his photoset of “Stone Footprints”. By finding the right stones and perfectly arranging them, Iain was able to make a number of very appealing pictures. For some reason, these “footprints” look adorable. It could have something to do with the cartoony appearance that they have. In our opinion, the finest photo out of this whole set is the one with a large footprint and a smaller one on top of it, as if a child has stepped into the footprint left by his or her parent.
