Business portraits, like businesses themselves, are typically bland and uninteresting. This has little to do with the ability of any photographer and everything to do with the vanilla tastes of too many companies.
Low creative expectations aside, corporate portraiture can be lucrative if done in an assembly line fashion. The upside to the client is a consistent look from subject to subject. This kind of photography requires just one setup per location and someone to marshal the subjects in and out for maximum efficiency.
This kind of work pays the bills but won’t stoke any artistic fires.
I’ve been lucky to have great clients who allow me to break out of the yearbook mentality and craft unique portraits of people on location rather than on a flat background.
