The idea of a photo walk is hardly new. I tend to understand such adventures as exercises for photographers in which they explore a location together and capture what they see.
Some photographers are now altering this social experience somewhat to explore a location for the benefit of those unable to explore (or no longer able to explore) that location for themselves. The idea of virtual photo walks using Google+ is to take images following the directions of someone else:
By rigging their smartphones to cameras, the photographers take directions during from virtual participants who tell them to snap photos of a particular tree or walk down that road to show them what’s beyond that ridge.
A smartphone I would think would be the easiest way to do this. The immediacy of the experience would be great. Photo quality would be acceptable. What a great base for a classroom project – the variations seem endless.
