Rye whiskey is an old school classic best served in a heavy bottomed highball glass, neat, or in this case over a single ice cube that is almost as big as the glass.
The rich amber whiskey hues contrast with the texture of the ice. Whiskey adverts are famous for subliminal messages and some even altered the photographs to create hidden images. If you look closely at this one, you might see a raging bull with a ring through his nose. All created by light, ice, whiskey, and the iPhone camera. No Photoshop necessary.
Moving the camera a bit introduces some fiery yellows to the concoction.
Tilted back the other way and the amber turns more to the red, and while the bull is back; he is further away, but I think the sight of red has angered him and he is about to charge!
