I've been struggling for months with how to present this wine's very nice label. It was while making this other photo that I realized I would frame the label with the outline of just one side of the bottle. It's in that context that the photo shown below is a display of a wine label, not a display of a wine bottle. I won't be surprised to learn that the unusual concept is not appealing to some people, but it works perfectly for me.
Setup
First Capture: A background of black velvet was in the center of a larger, circular diffuser. A medium continuous-light lamp behind the background and diffuser was shining toward the subject and camera. That created a bright outline on both sides of the bottle, though the outline on the right side was digitally removed during post-processing. A strip box touching a panel of translucent vellum at about a 45-degree angle on the left side of the scene was fitted with a speed light. That created the subtle gradient on the left side of the bottle.
Second Capture: A small continuous-light lamp high and on the right side of the bottle lit the label to create a shadow, which helps define its shape and depicts the red "S" as if it is springing upward from out of the shadow. That lamp also brightened the dark area of the label to ensure separation between it and the darker, adjacent areas of the scene. The label from the second capture was merged with everything else in the first capture.
