The screenplay called for a "close-up of Alma with a strange resemblance to Elisabet". On Fårö, Bergman conceived a shot where Ullmann and Andersson's faces merge into one. This was done by lighting what Bergman considered the unflattering side of each actress's face in different shots and combining the lighted sides. The actresses were unaware of the effect until a screening in the Moviola. Neither actress recognized herself in the resulting imagery, each assuming that the shot was of the other.
