When you hire a wedding photographer you are not just hiring them to provide a service, yes they will be there all day taking photos, however for a wedding photographer that is just a small part of the job and what you are paying for. Once they day is over your photographer will go away and edit your photos, over the course of the day they will have taken hundreds if not thousands of photos.
Do you really want your photographer to just go and print all these photos off and give them to you? Wedding photographers are not hiding anything from you, however what they are doing is putting together a beautiful story.
If you go and watch a film you know it has been edited, on DVD’s you can watch different ending sometimes and you can also see deleted scenes, some of the scenes are not needed for the film or the storyline, when it comes to the end there are different scenes, however there maybe only one ending that truly reflects the story and that is what is used.
Again the same can be said to a book, it would be like asking a photographer to hand over a memory card, USB, or DVD of raw images is akin to asking an author to present you with their book in manuscript format, unedited, unformatted, and including the paragraphs and chapters that didn’t make the cut.
