Most states also have a Film Commission Office which can provide information on locally shot film productions and the union affiliations involved. They also can inform you of the agencies that are known, and even more important, utilized by the casting directors and productions within the state. Again, take time to call these offices for information and with any questions you may have. Not calling is the first sign of a series of mistakes and not using your common sense. Pictures are necessary, however, maybe not as many as you think.
Many actors start with a snapshot sent to local agents to see if anyone is interested.
Portfolios and composite cards are used by models and those doing commercial print. Different cities want different kinds of photos. Take time to find a photographer who knows what that demand is and who is recognized by the agents and casting people. Moreover, do not pay to have your picture put in a book by someone who comes to your hometown and says you ll be seen in all the major markets. Agents want to contact and see you , not a book.
