Here's the difference between the two images.

[–]SidewalkPainter 74 points75 points ago

If a child ever asks me about the differences between men and women, I'll just use this.

[–]original_evanator 19 points20 points ago

What's kind of cool is you can rotate and translate the eyes and mouth and, voila, you've got the reproductive differences too.

[–]Hopulus 25 points26 points ago

this is one of the creepiest things i've seen :(

[–]STEVE_H0LT 17 points18 points ago

It's just a black image for me. Am I missing something? I feel like I might be getting whooshed soon.

[–]bayyorker 26 points27 points ago

Adjust your monitor settings. The areas where the eyes, eyebrows, nostrils, and mouth are should all be darker than the background of the image.

[–]Skaarah 6 points7 points ago

Just turn your volume way up. It's also one of those things you need to stare at and kind of cross your eyes to see the picture.

[–]Casual_Castrati 1 point2 points ago

Just grab a flash light and point it at your screen to see it clearly.

[–]Bored 2 points3 points ago

Zoom in... if you dare.

[–]Dr_professional 7 points8 points ago

That is terrifying.

[–]arthurstone 7 points8 points ago

The lips on the left image are darker in comparison to the face. Is that an actual natural attribute of women's faces, or is it something we're conditioned to expect due to makeup?

[–]bbty 7 points8 points ago

Yeah, the first thing I though when I saw this is, "the higher contrast just makes it look like face on the left is wearing makeup." It's pretty obvious that we're conditioned to react to makeup-wearing faces as more feminine than non-makeup wearing faces.

[–]iyzie 0 points1 point ago

It is natural. Anthropologists have found that the females of every ethnicity have, on average, lighter complexions than the males of that ethnicity. Evolutionists theorize that this may have been the driving force that caused someone ethnicities to develop white skin, through the process of sexual selection.

[–]thisissamsaxton -1 points0 points ago

Shouldn't the eyes and mouth be white since those weren't changed?

[–]WhipIash 1 point2 points ago

So.. just the contrast?

[–]onelung 0 points1 point ago

is that supposed to be mascara?

[–]DigitalChocobo 89 points90 points ago

Here's another illusion where faces that are side by side become ugly:

[–]WhipIash 28 points29 points ago

That was strange. It's even stranger how I could recognize Hugh Laurie and Nicolas Cage in my peripheral vision.

[–]thisissamsaxton 11 points12 points ago

Caricatures!

[–]mrdoink20 8 points9 points ago

I don't know what this is meant to do but it hurts my head.

[–]pestdantic 8 points9 points ago

Reminds me of the stranger in the mirror illusion. It's simple, just stare at your face in the mirror in a dimly lit room for about a minute.

http://mindhacks.com/2010/09/18/the-strange-face-in-the-mirror-illusion/

At the end of a 10 min session of mirror gazing, the participant was asked to write what he or she saw in the mirror. The descriptions differed greatly across individuals and included: (a) huge deformations of one’s own face (reported by 66% of the fifty participants); (b) a parent’s face with traits changed (18%), of whom 8% were still alive and 10% were deceased; (c) an unknown person (28%); (d) an archetypal face, such as that of an old woman, a child, or a portrait of an ancestor (28%); (e) an animal face such as that of a cat, pig, or lion (18%); (f ) fantastical and monstrous beings (48%).

EDIT: To me this effect explains the mechanism behind the Psychomanteum which was sometimes described as a small mirrored room with a single candle which was used to speak to the dead.

[–]windyfish 2 points3 points ago

That's fascinating. Thanks for that link.

[–]jacobo 5 points6 points ago

now, this is the best illusion of the ....millenium

[–]SerTapsaHenrick 2 points3 points ago

That was really great, thanks!

[–]CrystalKU 2 points3 points ago

Anyone have a physiological explanation for this?!

[–]DigitalChocobo 3 points4 points ago

I think wires sort of get crossed. Our brain mixes the faces, so we see characteristics of one face superimposed on the other. While either face could be attractive separately, they look almost nonhuman when they're mixed.

As to why that happens... not a clue.

[–]frenzyboard 4 points5 points ago

It's taking advantage of your brain's solution to the blind spot on your retina. There's a part of your retina that can't take in light because the optic nerve is attached there. To compensate, your brain takes images from your periphery vision and uses the information at hand to fill in the data as best it can. The result is an uninterrupted, though not entirely accurate field of view.

[–]FaithyDoodles 1 point2 points ago

So, between the faces looking normal and really ugly, there's a mid ground where it's sort of hard to even recognize it as a face. I wonder if that's sort of what it's like to not be able to recognize faces.

[–]wauter 1 point2 points ago

Somebody who had that condition did an AMA on that once. Ha, found it: http://www.reddit.com/comments/tfymn/c4mch3q/?sort=best

Why don't we say bi and call it a day.

Because they are only seeing one gender. If anything we're bi for seeing both.

How many cups?

[–]givequicheachance 38 points39 points ago

That is not a simple change in contrast. They reduced quite a bit of the contrast in the eyelids and lips.

Here's what the picture on the left actually looks like with the contrast increased--still like a woman.

(Animated)

[–]jhaluska 14 points15 points ago

That's what I thought as well. The selected changes in contrast changes the perceived structure of the face.

[–]imbapwnn00b 5 points6 points ago

Could it be that darker lips and eyes simulates makeup?

[–]wauter 0 points1 point ago

Rather the opposite: women put on make-up because darker lips and eyes are associated with feminine looks.

[–]imbapwnn00b 6 points7 points ago

wasnt that what i said?

[–]Sigmag 2 points3 points ago

No, makeup simulates darker lips and eyes; darker eyes and lips don't simulate makeup.

[–]imbapwnn00b 0 points1 point ago

On a greyscale picture, darker eyes looks like eyeshadow and mascara, while darker lips looks like lipstick. See the gif for yourself.

[–]BorgDrone 24 points25 points ago

Both were ambiguous to me, didn't see the left as female or the right as male.

[–]realityisoverrated 8 points9 points ago

It's not that complicated, really.

It's not absolute (of course), but more defined features are usually masculine. Our brain assumes that because it's so often the case (and has been for thousands upon thousands of years, which is why it's a latent, biological assumption).

Disney utilized this with Mulan. She looked very feminine and also very masculine simply because of one added feature: cheekbones.

[–]pestdantic 0 points1 point ago

Hmm reminds me of that fox domestication experiment. Foxes that were bred to be more docile also changed other in other ways: curly tails, patched coats and softer facial features. Are women evolved to appear more domesticated than men?

[–]realityisoverrated 1 point2 points ago

Woo! Speculation. I love it.

Could very well be. I've noticed that the more inherent / unintentional a reaction or behavior is among a populace, the more likely it is to be biological. Men have notoriously considered themselves the "masters of the Earth," and only recently have begun to recognize women as equally comparable to men (finally).

I wouldn't be surprised if softer features tap into a visceral notion that men are more fit, further assuming that women are less so. It's unfortunate, socially speaking, but could suggest that beauty often correlates with inferred domestication.

I'm glad we've evolved past mere biological adaptability.

[–]pestdantic 0 points1 point ago

Yup. There's also the old diehard theory that red lipstick makes us think of a "happy vagina". So I'm glad to go with a theory with a little more science behind it.

[–]beau-tie 20 points21 points ago

I'm pretty sure the more female looking face on the left is the one with higher contrast.

[–]Twitchety 7 points8 points ago

If you'll notice it's lighter in tone, but it is the one on the right that has more contrast.

If you look at the shadows around the eyes and nose, they're much more easily seen on the right hand photo because they're darker in contrast to the rest of the face.

[–]Kleosi 6 points7 points ago

The eyes and the nose - sure, but the overall contrast is higher in the left image. I get what they meant; it just makes their statement confusing. In fact, here's what I got just from changing the brightness of the right image: http://i.imgur.com/9ShyZ.jpg

[–]Twitchety 5 points6 points ago

I think their phrasing is just shitty. They added extra shadow and adjusted the brightness, it looks like its not an actual contrast thing unless they mean the contrast between the two images.

[–]beau-tie 6 points7 points ago

I disagree. While his features may be darker the contrast between his skin and his eyes/mouth are not as large as the female.

[–]Twitchety 1 point2 points ago

That's because they kept the actual eyes and mouth about the same shade and darkened the skin. Doesn't change the fact that the shadows have more depth, creating a more masculine look.

Honestly it seems the trouble here is with their phrasing, not which picture has more contrast and why, because you are correct in that her eyes and lips are in high contrast to the rest of her skin.

Edit: Bah, screw me. Look at Kleosi.

[–]beau-tie 1 point2 points ago

Honestly it seems the trouble here is with their phrasing

Agreed! They picked certain areas to make higher contrast/darker so saying they "the contrast is higher" is an over simplification. Still a very interesting picture.

[–]TwoLives 0 points1 point ago

It is. Isn't it? No you're even confusing me. The guys face is on the left?!

[–]EatATaco 3 points4 points ago

They both looks like boys to me, the one on the left just looks younger.

[–]tankgirl85 0 points1 point ago

I saw two boy faces, one with eye shadow and one without :( I thought it was a guy dressed as a woman comparison.. I fail at optical illusions, I don't see the sail boat.

[–]PatternOfKnives 1 point2 points ago

There's definitely more than just contrast altered here. The female one clearly has darker lips compared to the man, which is nothing to do with contrast!

[–]Waagwai 0 points1 point ago

The "girl" picture looks like a girl because her face is more pale while her lips are darker.. making it look like she's wearing some sort of lip gloss or lipstick.

[–]neodiogenes 1 point2 points ago

And a slight trace of eyeliner as well.

No big secret here -- it's just duplicating the effect of the makeup that women use every day.

[–]MrSuitMan 0 points1 point ago

It's because lipstick.

[–]Trolly_McTrollerson 2 points3 points ago

joke's on you, i fapped to both

it's a trap

[–]dave_felix 0 points1 point ago

Jedward?

[–]LaOddOpe 1 point2 points ago

I thought it was due to the lack of shadows making his face look less angular/masculine.

[–]Truck_Thunders 2 points3 points ago

They both looked like lady faces to me. really really androgynous lady faces.

Although the guy looks like a guy who looks like a girl. If that made any sense.

[–]aaronScooby 0 points1 point ago

wait the right one is the guy's face...

[–]Hotpotabo 0 points1 point ago

I can't see the difference at all. I can't even tell if it's a boy or a girl...

[–]sanfranman 1 point2 points ago

Saw two women

[–]theguesser10Space is deep 1 point2 points ago

This isn't an illusion. The picture on the right is darker, amplifying the various shadows of the face, this gives the face a more three-dimensional, or pronounced, look which is synonymous with males. It also makes the jawbone look less rounded and more rectangular starting from the cheekbones going down.

[–]Azabutt -1 points0 points ago

It's just because the eyes and lips look like they have makeup.

[–]pestdantic 1 point2 points ago

The question is why do women wear makeup to make themselves appear more feminine? Or why does makeup make us think feminine?

[–]jimii 1 point2 points ago

Probably because it accentuates the eyes and the lips, making them appear larger and prettier. Both large and pretty lips and eyes are considered attractive feminine traits.

Also because everyone else wears it and they don't want to be at a disadvantage.

[–]Zacivich 0 points1 point ago

I thought it was Sidney Crosby

[–]wellings -1 points0 points ago

By adjusting the contrast, you're essentially giving the one on the left the same effects as applying make up. This is no surprise at all.

[–]tragicallyohio 0 points1 point ago

I honestly only see a man's face here. Am I gay?

[–]tha_dood 1 point2 points ago

[–]AnalogPie 0 points1 point ago

[–]HiImTed 0 points1 point ago

It's the lips. Darker lips give the image on the left a more feminine look.

[–]the2ndtolastunicorn 0 points1 point ago

Did anyone else see a male in both photos? All I saw was two pictures of the same guy with the only difference being exposure/contrast.

[–]Mister_DGAF 0 points1 point ago

I feel like its just the lips :/

[–]willystylee 0 points1 point ago

I didn't think one or the other was male or female like my brain was supposed to according to this.

[–]The_Last_Melon14 0 points1 point ago

They both look like guys to me...

[–]AtlasAnimated -1 points0 points ago

It's a pretty big change though, the shading makes the eyes look more deep set, the nose more ridged, and the lips less rosy. Still pretty interesting.

Edit: What would have been more interesting is having a picture of the exact same face except within different contexts which give people the illusion of it being a man or woman. Shading it differently isnt that impressive of a feat. You could touch up a piece of shit and make it look like pudding with some subtle changes if you wanted to.
