My photos were made with a DSLR primarily with a 50mm f1.4 lens. I generally use a lower f stop in the AV mode to increase bokeh to emphasize the primary subject of the photograph. Some of the newer smartphones can provide a fake bokeh that in my opinion is easily discernible from real bokeh.. . . .
This brings up a point for taking the pictures. There is a real difference between using a smart phone vs a DSLR camera for taking pictures. In general smartphones don't really have the exposure control that DSLRs have. Smartphones are ok for snapshots but if you are looking for publicity shots it's just better to use a DSLR and know how to control the exposure, focus and depth of field. An off camera fill flash wouldn't hurt either. Of course, if you set a DSLR on the default general purpose program mode (normally called P) and use the built in flash then it's about the same as a smartphone.
