In my years as a photographer I have learned a few things about people. Once a commitment is made, they usually follow through. Inquiries, on the other hand, do not.
Many call to schedule headshot, portraits, weddings, family sessions, model portfolios, etc. Most follow though. Cancellations on the other hand are disrespectful to both our time management.
If you agree to a session with me, the a prepayment is warranted. I causes both of us to commit in agreement.
Thus, as a new practice, I will be taking prepayments before scheduling headshot appointments.
