The iPhone is not a cam­era, it just has a cheap plas­tic lens, a chip and some mem­ory ded­i­cated to cap­tur­ing and stor­ing image data. There are no adjust­ments pos­si­ble, all you do is raise the phone in front of you, push the but­ton and hope that some­thing some­where might be in focus. Now and again, even this prim­i­tive set-up catches more than mere objects, but a mood or a feel­ing. At 7am one morn­ing in Ams­ter­dam I noticed how no boats had been on the Heren­gracht, leav­ing the water untouched and as still as a pond. It made me get off my bike and take one of those quick snaps, with­out con­sid­er­ing expo­sure time, aper­ture or focus.
