Hi imagine you have to shoot in a white square box about 15meters long for a wedding cermony, how would you setup your lights? Like wise if the ceremony is in the same box but this time its all black, how would your lighting setup change?
My approach for both cases will be a sandwich lighting with a lighting 2:1 ratio, shoot closeup with shallow dof. I can not think of any other way which will produce decent images. If you have better ideas I would love to hear it.
