The waterfalls were impressive, but from what I could see, most of the people were  even more impressed by, well, themselves. I saw very few people taking pictures of this nature's wonder, but almost everyone was taking selfies. Is this a cultural phenomenon? A psychological phenomenon? Or, a technological one?

Random Observations on Art, Photography, and the Creative Process. These talks focus on the creative process in fine art photography. LensWork editor Brooks Jensen side-steps techno-talk and artspeak to offer a stimulating mix of ideas, experience, and observations from his 50 years as a fine art photographer, writer, and publisher. Topics include a wide range of subjects from finding subject matter to presenting your work, and building an audience. 
Included in this RSS Feed are the LensWork Podcasts — posted weekly, typically 10-20 minutes exploring a topic a bit more deeply — and our almost daily Here's a thought… audios (extracted from the videos.) Here's a thought… are snippets, fragments, morsels, and tidbits from Brooks' fertile (and sometimes swiss-cheesy) brain. Usually just a minute or two. Always about photography and the art life.
