Hi jjj,
This shoot was aimed at folks who may have a fancy new phone, and don't own a Dslr or a digital back. I'm just showing how far one can push the phone camera with just a bit of affordable gear of ebay. Even in good directional natural light, this phone takes amazing portraits, which you can print sharp at 12x18inches. And if the internet is the final destination, you can't tell the difference in small size.
People use their phone to take snapshots, its perfectly fine. You should always use the best camera at your disposal. There are some photography lovers who take snapshots with Canon 5ds or even with PhaseOne. I chose the phone in the home made studio just to experiment, and it was a great experience.
