I have a photo that was taken by a third-party photographer (i.e. I was not the one who postprocessed it). I've been told by a number of people that this photo looks unrealistic, more like a computer-generated render than a photo of a real-life place. I can see where they are coming from, as this photo looks a bit off to me as well. However, I can't pinpoint the reasons why it doesn't look real.
Can you all help me articulate why this photo looks unrealistic? I believe it has something to do with the condensed dynamic range — the shadows seem to be rather nonexistent, and there aren't many highlights. However, I can't figure out if this is the only reason, or if there are more factors contributing to the lack of realism.
