Here is a photo I took this afternoon of an egret fishing.
Look closely at the fish’s face. At a quick first glance, do you see what appears to be a fish face kind of looking down with one red eye and one black eye and the bright highlighted spots being it’s mouth?
Or… do you see a face looking up with that red spot being the fish’s mouth and that black eye is it’s left eye with a tiny portion of it’s right eye appearing at the top?
Do you see both scenes? Do you need to refocus your eyes to see both? Which did you see first?
The second scenario is the correct one, what initially may have appeared to be a red right eye is actually the fish’s open mouth. Who saw that right off from the start? 🙂
