You may have seen this illusion. Look at it close-up, and it is Albert Einstein. Back away a few feet and it is Marilyn Monroe. What is going on here? You’re seeing the effects of frequency resolution.
Close-up, you’re seeing the finer detail that is familiar to you as details of Einstein’s face. When you back away, that detail is lost lost to you as distance blur and the softer, less detailed information in some sense comes into focus as the curves of Marilyn’s face.
It’s a little bit spooky and an initial takeaway might be that seeing is not believing.
