I used a reference photo and a set of calipers to measure and model the bottle's features as closely as possible to the physical sample I had to work with. The contents of each was photographed on white and isolated in photoshop, then manipulated to fit on a UV unwrap of the "contents" mesh which is a simplified and scaled down version of the bottle itself. This is a two-light setup with an overhead key and a meshlight for highlights on camera right. There is a black mesh to act as a flag (also known as negative fill) on camera left, to help add some contrast.
