Having an Engagement of a Prenuptial shoot in the days was not a common practice or actually not at all. But now this is always part of the Wedding process. Others may disagree but having an engagement or prenuptial shoot is a good practice for so many reasons. This will help the couple to practice and at the same time to be comfortable with their Photographers or Videographers. When the big day comes they are more confident and should be better subjects as well, sealing the output to be perfect!
