RE: Humiliation is the worst type of punishment for anyone to experience.
Yes humiliation should be added in a large dose to any physical punishment. The belt, the paddle, the cane, a hot soapy enema, should all be done in front of the family, the classmates or the sought after romantic interest.
Humiliation makes the punishment more effective, remembered and a future transgression is less likely. Humiliate before, during and after the punishment for effective behavior modification.
Pics and video is are a good reminder of the punishment and are excellent for humiliation.
