That's beside the point. The raw files are not a finished product. It would be like ordering a cake from the bakery but asking for delivery of only the ingredients and not the cake. I don't know any wedding photographers that print the image exactly as it comes from the camera. First, there's editing of the complete set of shot images down to the ones that will be edited, then there's editing of those to a final image.
Yet, IKEA is a very successful company. They don't sell the finished product. They sell kits to build your desk/dresser/etc.
IKEA is happy to arrange delivery and actually build the product, but these are extra cost services.
There are many business models.
A good photographer will not and should not share their "outtakes". Only show your best work, period.
While this is oft repeated advice, it is just one way of running your business.
I know a lot of local pros, and not one would even sell the raw images. They are not the final image.
Again, this is their business model.
There is nothing that says every photographer must have exactly the same business model.
Some photographers never provide files. They only sell prints. They position themselves as high end artists. They charge a fortune, then spend a good percentage of that marketing themselves.
10 years ago this was the typical model, but times have changed. In todays market, it's much harder to be successful if you refuse to provide digital files.
Some photographers only provide files, and don't offer prints.
In order to be a successful photographer you need to offer what your clients are willing to pay for, or you need to convince your clients to be willing to pay for what you offer.
There absolutely is a market for clients wanting all the images from a wedding. Even the bad images. For many people, it is not the quality of the images that's important, but the people in the images. These are their friends and family. In 20 or 30 years, they will look back at their friends, and smile and laugh. You could give them images from a locked off security camera and they would enjoy them. It's not just the beautiful album that has value, but the actual images that show people as they are. Sometimes the images that don't show people at their best, are the ones we want to see in 20 years. These are the images that show people as they are, not the images that show people as they want to be.
It is not uncommon to see outtakes behind the credits of a movie. People enjoy the less than perfect images.
I am not suggesting that every wedding photographer always give every image. I am suggesting that it is not a crazy thing to offer every image. In fact, I can see it as an additional marketing point. Most photographers only give you the images they think are good. Hire me, and you also get all the images so you have more memories of your special day!
