Do I have to look at the front to take a photo of the marriage certificate?

You don't have to look forward. When getting the marriage certificate, look at the top of the center of the camera, which will be more energetic. The photographer said that smiling at 2 o'clock would be more beautiful as a whole. If you look under the camera, your eyes will look small, or your chin will look like double eyelids. If you look at the middle of the camera, your eyes will look dull.
