We can go out “on assignment” (whatever that means to you) with our DSLRs, shoot, go back home, offload our CF cards and produce terabytes of pictures that could be printed the size of billboards (but, for the most part, won't be). That's only one mode of operation, though. There are other modes that work out differently and
yield different results, but are
equally valid (for different purposes).
What this guy Chase Jarvis
is saying and doing may seem of limited relevance to professional photographers, but I've been using my phone camera a lot to push spontaneous imagery to places like Facebook, and I think he's chipping away at one end of an increasingly big topic.
For me, Lightroom has been an enormous leap in terms of workflow. In retrospect, I think enabled me to focus on pictures, not picture
files. Meanwhile, my DSLR is a cul de sac: I can shoot all I want, but I cannot do anything with the images until I go home and import the imagery through Lightroom. By contrast, with the crappy camera in my iPhone, I can snap a picture and post a version of it to the Internet (for whatever purpose) in a matter of seconds. That capability may mean something slightly different to me than you, but that's precisely why it's a big deal.
