This is my first photo of this decanter using the bright-line method, which creates a dramatic mood.
Setup
A large continuous-light lamp with five bulbs is behind the subject shining toward the camera through a large circular diffuser and around a background of black velvet. The tabletop is black fabric. A small continuous-light lamp with a diffuser sock is to the right of the camera lighting the hand. A flag with a rectangular opening in the center is placed in front of the camera lens to eliminate flare. ISO 800, shutter 1/30, aperture f/5.6
Please view in the Lytebox. If you can't see separation between the wine and the background, it might be because you're not using a profiled and calibrated monitor and/or not using Firefox.
