TZM Photo requires a retainer in order to save the date of your event. A signed contract also obligates us to do business with one another. These are both required in order to book an event with TZM Photo (Zach McCormick). TZM Photo retains the rights to use all photos in advertisements and social promotions. TZM Photo will keep these files, which may be used months or years after the event. The customer also retains the rights to print all images, but not to alter any images or edit any images in any fashion. This would, in turn, corrupt the contract with TZM Photo and possibly cheapen the work. 2016, TZM Photo.
