I have a great deal of difficulty recognizing faces, especially if I haven't - if I've just met somebody, it's hopeless.
Our eyes and brains pretty consistently like some human forms better than others. Shown photos of strangers, even babies look longer at the faces adults rank the best-looking.
Our brains are wired to interpret shapes as faces and bodies. That's why people see the Virgin Mary in the clouds or even in cheese sandwiches. It's your cytoplasm, not some strange ectoplasm.
From the first shock of the contemplation of a face depends the principal sensation which guides me throughout the entire execution of a portrait.
When I look at someone's face, there's something in my brain that just clicks - that breaks down their face into the elements that go into a caricature. It might be like the way a chef tastes a dish and can break down into elements what went into it.
What you're getting excited about is not A face, but a feminine face.
Regardless of your sex, if you have elevated testosterone levels in your blood, you're more likely to think a face with a neutral expression is instead looking threatening.
The eye instinctively looks for analogies and amplifies them, so that a face imagined in the pattern of a wallpaper may become more vivid than a photograph.
