Is it too much for the photographer to send all the original films?

You didn't ask the photographer to send all the original photos, but asked the studio to give you all the negatives of your photos. First of all, all the negatives of your photos should be given to you free of charge, but some photographers may destroy all the original films, because poor photos will affect the reputation of the other party. Like these have been destroyed, they may not be able to give it to you, others should be able to give it to you.
