Factual error: Albert and Emma pose for phony wedding photographs in front of a green chromakey screen in order to have a new background created on computer. However, Emma is holding a garland of flowers surrounded by green foliage. You can't have anything green in the foreground when using green chromakey as it will drop out too and become part of the superimposed background.
Suggested correction: "Green screen" chromakey can be set to very fine tolerances. The garland of flowers Emma is holding is a much darker green than the chromakey curtain behind them and could easily be incorporated into the completed composite photograph.
