My wedding is Saturday and I have two photographers. They are a father daughter team and they are their own business. No one else works for them and they don't work for any sort of larger company. I have heard that you shouldn't tip someone if they own the business, but I'm not sure if this falls into that category. I'm also not really sure if they would be considered just independent photographers, or co-owners, or if the father is considered the owner, with the daughter working under him. Any thoughts?
