Photographing glass and dark liquid is always a  challenge. To illuminate the liquid without diluting it, required some creative lighting. The label was also a metallic foil which needed specific lighting to show off  the reflective foil. The overall general light was attained by placing the bottle within a translucent tent. The label required a metallic fill light very close to the bottle to provide the highlights. The bottle is on a clear glass pane with a hole cut in the black paper. (Same technique on black and white paper.) A light was placed below the base and then reflected thru the bottle back to camera with another metallic foil card, behind the bottle. This provided the translucent detail and color to the product.
