Digital photography has one advantage over anolog photography: EXIF metadata. -- The digital camera automatically records date, time, shutter speed, aperture and a whole lot of other things for every picture taken.
In analog photography the photographer has to scribble all that on index cards or the like and immediately problems arise: It's Sunday and all cards are used up. The camera is here and the card for the current film is on the other side of the world. There is no more space left on the card. Where's that .x@#.. pencil?
Well, why not use a smartphone to scribble down the index cards: It is never full, always there, no pencils. Since Creevey is not telekinetic you still have to enter the data manually, but it is a lot easier.
