Over on Light Paths, Gary has a good article about iPhones and photography as a cultural activity. He compares the Kodak Box Brownie to todays iPhone.
In my early years of studying photography this kind of image would not have been considered. The success for me about this image is the mixed lighting sources firstly. Secondly the brief moment where the woman is glancing down on the CRT TV. These things combined with the kind of meta reference of the shadow of the tree outside. As an indexical marker a nice reminder of the light outside.
