I definitely have backup equipment (see details in Equipment question). This is probably on of the major differences between an amateur and a professional photographer – I have a backup or replacement for every single thing – batteries, lenses, flashes, cameras. There is no way my equipment will fail and I won`t have a replacement to keep going and capturing your special moments.
I will be doing everything humanly possible to photograph your wedding, but in case something happens to me that will affect the quality of my work, I will provide you with a replacement photographer I`ve worked with previously and can guarantee the same quality of work. That is why we are signing a contract, as it is protecting you as a client if a case like this occurs.
