Today I tried the beer in a glass shot. From what I have known for some time is backlighting is key. On this shot, there was a light behind the glass on the right just off frame and one on the side of the glass on the left. With very little touch-up in Adobe Lightroom here is the final shot. A couple things I am still wishing for are a third light, more wattage, and some fizz tablets that would have made more head on the beer.
