I was a foreign photography student who just moved to Prague, I donít know the language at all. I went to the most famous old town square during the Christmas period. Thereís lots of Czech families and foreign tourists are having photos in front of the big christmas tree. I asked them if I could take a family picture of them, then pair some of the family members with passers to make another fake family photo.
