Plitvice Lakes is a popular place for tourists. This photo was made from an observation deck above the lakes on my camera Canon EOS 650D. And I sign all my photos. The watermark can be seen in the lower left corner of the photo.
You are right. The photo does not claim to be uniqueness because there are many photos on the internet from this place.
If I'll have a bit of free time then I'll look for another photo.

Hi @xpilar and @sultan-aceh

Thanks. Best regards, @euggud
