Why don’t you send all the negatives from Aermei’s children’s photography?

I have asked this question before, and I don’t understand it, because many of them send all the negatives, but why is it different from others? You will know after you go there, and after taking pictures Each series will be shot multiple times, so that people can choose, and some good-looking ones will be retouched, while the rest of the negatives will be unprocessed
