At royal weddings, it is customary for the bride and groom to salute the Queen. I looked for six wedding profiles, the first three of which were photographs of Charles and Diana, Andrew and Sarah, Edward and Sophie saluting the Queen at their wedding. The fourth is of Kate and William, and the fifth is of Princess Eugenie when she was married.

The last one is Harry and Meghan, and from the photo, only Harry is performing the salute, and Megan doesn't seem to have it. But judging from the video, Megan may have been too nervous at the time, not only was her movements not standard, but she was also particularly fast, so she didn't take a picture at all.
