His method of work typically entailed careful preparation for the shoot, with the lighting and studio props (of which he used many) arranged in advance. His instructions to models are remembered as being brief and to the point. His published work uses lighting to pick out the subject; he frequently used four spotlights, often one of them pointing down from the ceiling. Only rarely do his photos include shadows falling on the background of the set. Horst rarely, if ever, used filters. While most of his work is in black & white, much of his color photography includes largely monochromatic settings to set off a colorful fashion. Horst's color photography did include documentation of society interior design, well noted in the volume "Horst Interiors". He photographed a number of interiors designed by Robert Denning and Vincent Fourcade of Denning & Fourcade and often visited their homes in Manhattan and Long Island. After making the photograph, Horst generally left it up to others to develop, print, crop, and edit his work.
