I excepted the wineglass-competition and here are my own two cents.

The lightning was relative complicated, because i wanted the candle to lit the scene, which produces a lot of noise, especially at the glassmaterial. So it was a lot of tweaking with extra arealights and hdr lightning.

For compositing i used imagestacking ([http://blendernerd.com/image-stacking/](http://blendernerd.com/image-stacking/)) to further reduce noise , a glare node and some colorcorrection. There´s still a lot of improvement possible, but i´m through with this scene and want to do something else. :)
