If you need to reschedule your session, the deposit will be held for your new date. In the unfortunate event you are unable to go through with the scheduled shoot, you may cancel but you will forfeit your deposit. Any rental space fees will be moved at the discretion and availability of their reschedule policy.
On my end, unless I am too ill or injured to perform, I’ll be there! In a worst case scenario, I would make every effort to find you a photographer to step in that reflects my photography style closest. In this instance only would a client be entitled to a full refund, including the deposit. Though rare, I may suggest rescheduling the shoot if the light or significant weather are likely to reduce the quality of my services, and only if you agree.
