Hide photos & videos from the gallery

no matter what is stored on the Android operating system as long as there is no root rights needed to view this photo / video file stores in my case Amazon photos. All photos & videos of the file system in your app or the pictures are released. But I do not want my photos and videos I automatically enter the gallery in another place like downloads / documents. Unfortunately, I always have to go manually in the Amazon Photos app and hide the pictures that do not come from the camera which time unnecessarily wasted. ---------- EDIT: After the hint of the community bot in the comments, I'll try to make the question simpler. No matter where I save photos and videos on my device, for example in the music folder or in the documents folder, they end up in my photo gallery. But I don't want them to get into my gallery because the pictures are in the documents folder and not in the camera folder. What exactly can i do now?
