Following a tutorial from Andrew Price from Blenderguru I wanted to create a beer advertisement (simply for fun and as German Octoberfest is only 2.5 months away). Model is from myself (beer glass) and the shading is after the tutorial, but adapted to fit what I needed. I changed the absorption and also mixed a tiny emission into the beer to have it get brighter - this seemed to help a lot (although physically totally incorrect). The image was post produced with Photoshop to add the elements and the vignette, but compositing done in blender for glow and getting rid of most fireflies).
