Tony Walthamâ€™s day job has always been as a geologist, but this has given him the opportunity to travel the world taking photographs. In his youth he was a caver, and started creating underground images. But while his photography matured, so too did his body, so that he now sticks mostly to taking pictures above ground. He travels widely, usually in pursuit of a geological theme and specializes in photos of geological features, usually with his wife in there for scale. Volcanoes, sinkholes, great landscapes are his favourites, but the human world always grabs his attention, whether he is in the Yorkshire Dales, on a Chinese mountain or in an Indian village.
