Walkthrough or surround?
Kitchens are usually in one of two configurations....cabinets in the surround or a galley walkthrough kitchen. Your photographer must be able to capture the correct perspective when taking the images in order to present your kitchen in a positive light.
Eat in or Gourmet?
Some kitchens are eat in rather than having a separate dining room. These are usually difficult to photograph since they should be photographed from a perspective that shows both the kitchen area and the eat in area so the online viewer can get a sense of traffic patterns. Gourmet kitchens need to be presented so as to showcase multiple work areas, large islands, high end appliances, warmer drawers, and plentiful cabinets.
