I went to the photography studio to take wedding photos and bought photos of 100. They only gave me the post-ps photos, not the original photos. Do I have the right to the original photo? How to defend rights? Well, it depends. My buddy's studio is like this. The main reason is that there are not enough people and equipment. A lot of people will take pictures a day. Many computers are full of folders. I was dizzy when I saw it. It was normal to delete it. But if you want 3600, it should be a big store. Hard disk is still affordable, right? It can be restored after being deleted. Which customers can't be deleted? Don't you understand? This request is reasonable. Every time I develop my own photography, I will back up the original picture myself. Say hello to the boss and leave me two copies in RAW format. Don't delete the owner. He is easy to talk. You reason, he listens.
