Photographer Rob Grimm has posted a nice little BTS of his 'Micro Brewery Project' - where the photographs feature some various beers from the United States based on "unique bottle design, label, and/or flavor profile." The video starts out with a great, little trick for creating an even pour in a photo. The bottle itself is clamped in place, but by using twine, nail polish remover and fire, you can cleanly remove the bottom. With the bottom removed, you are able to get a less messy pour as well as a little bit more liquid into the glass.
In the end, you will see that the final shot is a composite - the glass and bottle, the beer and the cracked ice background are cherry picked. He also doesn't go into detail on the lighting specifics, but from what we can tell (and the glimpses are pretty quick), it looks like:
Remember to use caution when lighting glass on fire, and don't forget to sand down the edges.
Thanks @RGGPhoto for sending us the tip!
