It's just a picture?

Gtfo normie

How do you make these? I found this one on /qa/ awhile back and they have much potential.

could anyone explain what this is about?

Wow you must be autistic or some fag from reddit who thinks that's all that gets posted on Sup Forums.

...

it's an old trick that exploits the png gamma header

Can you explain in more detail? I'm amazed these aren't more popular given their trolling potential.

wtf? dude

basically, you take two separate images and interleave them in black and white
the "white" pixels in the picture contain one image, stored at a much higher intensity, i.e. very bright.
the "black" pixels store the other image, stored at a fairly normal intensity, but scaled down to near black with the gamma correction.
the image contains a gAMA chunk specifying a file gamma value of 0.02.

when displayed without gamma correction, the viewer sees the first image with "white" pixels interspersed, which are actually first image at its original (high) intensity.

when displayed with gamma correction, the viewer sees a colour-corrected image with "black" pixels which are actually the second image rendered at a much lower gamma value.

I didn't know I had this fetish until now

Bump

How can I view these correctly on my iphone

get a browser that supports png gamma correction

Put sharpie in poopper and take picture. It will flash the software on your iPhone

how is this done?

Basically this, not even Fortune displays this correctly

any tutorials to do this effect?

pretty cool but is there a none version of that? struggling to read it lol

imgur.com/gallery/UG4v9 details a manual technique

but the easiest way if you've got access to a linux/bash shell is to use a script which utilizes the imagemagick convert method.

You could also use TweakPNG on windows to edit the gAMA chunk of the PNG

that's what the first method i linked uses.

Oh, sorry haven't see it

What am I supposed to be seeing here

Something truly magical. it's called rape

(dunno how well it looks like this) but basically its a "morphing" photo

Forgot, above thumbnail, below expanded image

You mind doing this for the rest of them?

Not at all, gimme a minute

bump

...

So how do they work?

see

...

...

and as far as how this works on Sup Forums, the gAMA chunk is stripped from the thumbnail image during creation, so you see the non gamma corrected "first image" in the thumbnail, but when you click and load the full image, your browser renders the image with gamma correction which appears as the second image.

...

Done mah man

...

i like this one

[OPENING INTENSIFIES]

more plz

Any site that can make these?

more like this

I don't know what this is

nice

You saved it as a jpg, you need to have it saved as a png for it to still work. You may have ruined it.

bump

You could use double vision

...

i'll see if i can pump out a generation script page in a bit.
