This is a process known as Pareidolia. The fact that we initially see a giant face in the photo, even though it doesn’t fit the rest of the image, is probably not a coincidence. We have more neurons dedicated to promptly identifying faces than the ones that recognise Victorian kids sitting on their dad’s lap. That’s why pareidolia happens so often with faces. You don’t usually see Victorian kids in the clouds.
