Single Light Source Photo - an example

Like most boys, Ben loves cars. One day, I noted that he invented a "car park in the air". This is a photo taken using primarily single light source - light bounced off from a white umbrella.









The umbrella flash is triggered from the camera flash (via hotshoe adaptor), which point toward the ceiling. In fact there are two flashes, but I consider it single light source since the umbrella flash is much stronger than the camera flash. The camera setting is at ISO100, f11, 1/125s. This the umbrella light source front of the subject. The relative position of the subject, umbrella light and the camera can be seen from the following picture.
