I go this email the other day and thought it was brilliant!

Everyone has a wedding contract, but how about an album agreement? Albums are be the most expensive single item a wedding and portrait studio can offer. Not only is it the most expensive product for the client, it is also the most expensive product for the studio.
Protect yourself with an album agreement just like you protect yourself with a wedding contract. Nothing can be more costly than having to reprint an album due to a miscommunication about the design or cover choice.
