>>3273248Because photography is not only about art, but about the photographer, too. I assume you are referring to tourists taking the billionth shot of some attraction. They are not creating art, but memories.
Of course
>>3273255 is right, too.
Pic related is perhaps the billionth shot of that river loop.
The difference is, this here is mine. I can come back to it in a couple of years and say damn, look what a shitty picture I took of that awesome subject. I can do it again then, and be good, and I could hang it on my wall and say, I was there, I saw this, this is what I made of it.
