Why are there different types of contracts?
Each of the different contract templates have specific provisions written for the type of photography they reference. For example: A birth or wedding photographer may want to to contract for a required break, whereas, a general portrait photographer may not necessarily need that specific provision. There are other provisions even more specific to each type so over the long-term it’s always best to have a contract that speaks to the type of photography you’re shooting with the client.
If you work with general portraiture (or multiple types), the general portrait contract is a great place to start.
