My iPhone has become the most indispensable camera I carry. I have posted well over 1,000 photos to Instagram @PhotoJoseph from my iPhone, nearly all shot on the device itself. Recently I've taken to posting images shot on other cameras as well, transferred to the iPhone for immediate sharing in the field, therefore gaining the same "in the now" experience as those shot on the iPhone itself.
I regularly refresh this gallery with a recent trip, and in this case it's a trip to Portland and then down the Oregon coast. For more photos going back several years, visit the complete instagram gallery.
