As to 'following', the march around the globe to so many of the same sites by so many photographers makes the appearance of emulation more likely even if it isn't actually the case. Having pretty much chewed the Yosemite, Death Valley, Utah and Pacific coast sites to soft, easy to swallow pap, the hadj seems to continue to Japan, mainland Asia, Iceland, Tuscany etc.

One aspect of Bill's work I truly appreciate is that in spite of making some of the obligatory pilgrimages, he also pulls wonderful imagery from what's close at hand where he lives. Maybe other photogs will follow him home!
