I don't often work in a studio, much preferring the look of surroundings to featureless seamless. But a studio certainly makes it easier to do lower-key work and to control spill onto backgrounds.
Semi-pro model Dagna proved a delight to work wit; this was one of a series using a simple red sheet enhanced with some colored fill light and further warmed in editing.
