From a licensing standpoint, Pennsylvania is as moderated and even-keeled as its founders. Although the Commonwealth regulates a number of industries, it doesn't go as far as many states.

In Pennsylvania, photographers who perform services for money including at weddings, private parties and at commercial shoots must have the appropriate business licenses.
