I crafted a living room, using the old stage model. I wanted a abstract scene, where we can see the protagonist lighting candels while the electricity brakes.
This static scene should perfectly harmonize with the other rather shaky flashbacks! Somehow we achieve a nice contrast in any aspect (unreal-crafted footage) and it is awesome to see the warm candle projected on the actors body.
I use short bulb exposures each frame and let the protagonist move. I used ffmpeg another time to transform all the pictures to video.

The candlelight is added with mask-keyframing(thanks to Lucas)!
