A pendant lamp I saw somewhere hanging in front of almost perfect medium grey background in a perfect ambiance, it turned out to be more of a lifestyle editorial kind of an image.
This is again with an iPhone. The resolution of an image is not as huge as the DSLR but it isn't unacceptable, for example this one is 2354px x 1765px actual size, which for web I've converted to 1200px long side like any other images I resize.
The mobility, the reasonable resolution and to shoot without getting unnecessary attention is worth doing it with a smaller camera. I'm thoroughly enjoying it.
