My teeth were bleached to A1 teeth shade from a b2 shade. Why do my my teeth look fake in pictures? (photo)

The issue am having is teeth dont look white enough when am looking through the rear view of a car wing mirror however i attended a wedding and had pictures taken, my teeth appear to look unnaturally white almost like i have veneers, i wanted to ask is this a common practice, has other patients had similar problems i tryed searching online but cant seem to find any answers
