I'm sure that's true in many cases. However, I've seen other cases when Popular Photography highlighted setups used by people who were simply making photos in their studio to be included in their portfolio. No deadlines. No models or assistants being paid by the hour. No client on the set. In fact, no client waiting to see the photos. Yet lots and lots of expensive, unnecessary equipment. Perhaps they needed the equipment for shoots that are on a deadline and felt the need to demonstrate that they know how to use it.
On the other hand, I've seen tutorial videos made by one particular studio pro whose name I can't remember who explains the simplicity of producing quality shots with relatively little equipment. So, I know at least that pro takes that path.
