Ghost Spots and Ghost Photos form pairs, and obtaining a Ghost Spot activates the corresponding location. Therefore, players must first obtain the Ghost Spot from the opinion toll box before taking the corresponding Ghost Photo.

It seems that all or some of the pairs do not appear unless the difficulty is Hard. To avoid wasted effort, starting on Hard is highly recommended.

You can also minimize key and camera consumption by manually saving before obtaining the pair, registering the Ghost Photo in your collection, and then reloading. It's recommended to manually save before taking the photo in case the shot fails.

and I found a good video from YouTube.

It will be helpful
