Wow, never seen that trick before. Cool.

yea thats cool

Nice trick. Would love to know how to do that!!!:thumbsup

that was pretty neat...

huh? what am i supposed to do to see this effect? I look at it and nothing happens. What do u mean by 'select it'?

c'mon give it up! wtf am i supposed to see?

Thats fuckin cool

thats pretty damn sweet

click and drag across it so you highlight it

I don't get it either, I clicked on the pics and nothing happened.

Hmm, I'd guess the 'secret' image is a bunch of alternating pixels at very low contrast, with the 'front' image on every other pixel at high contrast. When you select, 'doze draws alternating grey pixels over the image, covering the front image pixels completely, so only the secret image is visible.

Very clever idea. :)

If they couldnt figure it out, they didnt deserve to know.

My browser doesn't select images like that. :(

Click some text above teh image, and keep dragging your mouse down over the image. (At least this works in IE on Windows...it wouldn't necessarily work the same way on other browsers).

Very cool effect! When you select an image normally, it turns every other dot white, in a checkerboard pattern. In these images, You have one image in one checkerboard, and another shifted one pixel to the right. You see the primary image because its colors are high contrast, although it's somewhat faded because every other pixel (the ghost image) consists of lightish similarly-colored pixels. When you select the image, the checkerboard of pixels in the primary image are all turned to white, leaving only the ghost image's pixels left...and even though they're low contrast (similarly-colored), that's more contrast than the all-white pixels they're next to, so you the ghost image stands out.

when you select the picture the first picture fully disapears , that never happens to a "normal" .Jpg , then may be there its the 'secret'

Jesus christ, CTRL A .

Its your comp, not your browser. Just hi lite it like you do a block of text you want to copy.


Geesh, its not that hard people.

that's great!!

iirc, gothweb has a mac. they don't highlight images the same way a windows machine running ie does. wouldn't work on netscape and i'm guessing it wouldn't work on a linux box either

oh, k. sorry

Bring this to teamphotoshop.com or something, they'll know perhaps.

Btw, where did you find those images?

some body sends to me the links to the .JPG files by mail...

xp wont----------:( -----------copy and see

What're you talking about? I'm using XP, and it's working fine.

Just press: Control + A

Some people just shouldn't be allowed to use computers.

Are you stalking me? If so, can you tell me where I left my frickin' spare key?

very nice, very clever, haha

actually, i have an insane memory and i can remember the most insignificant, random things.

as for your spare key, it's in the den.

Just tried making my own.

For photoshoppers, here are some steps to do this:

Put your primary image on layer one.

Put a checkerboard pattern of alternating black and null pixels on layer two. The top left pixel should be null, the one to its right and below it should be black.

Put your ghost image on layer three. You might want to lower the contrast a bit, or pick an image that doesn't have a lot of high-contrast edges in it, so it isn't as apparent in the final image. (The one I chose is rather apparent...not an ideal candidate).

Put a second checkerboard pattern of alternating black and null pixels on layer four, but shift it one pixel to the right of the prior checkerboard pattern. So the top left pixel on this one is black.

Now change the layer style from Normal to Lighten on layers two and four.

Save as a GIF, and you should be set!

I think it's some type of UFO technology...:eek2

There we go, thanks! :thumbsup

What am I missing? Your method seems to make sense, but it isn't working for me at all. I just end up with the bottom layer disappearing completely and nothing happens when I highlight the completed images.

Maybe you'd shoot me the PSD? I can't figure out where I am going wrong.

SpaceAce

yes please , post the psd

No? Come on, this is driving me nuts. Your method is not working for me and so far I am not able to figure it out from scratch. I'm still working on it, but I'd like an assist :)

SpaceAce

Ah-ha. I finally worked out a method on my own, but I am not satisfied. I want to know why I couldn't get yours to work.

SpaceAce

:thumbsup

Very slick!

Oz

I still want to see a PSD. The method I came up with shows too much of the ghost image, no matter what I do. Come on, someone who has got this working properly please post it.

SpaceAce

That doesn't work for me.

www.worth1000.com

There is a thread about it on the forum there.

Too late, I dicked around until I figured it out :)

The file sizes are a little big because I didn't want to compress them very far and the second one shows through a little (I could have made it not show through, but it didn't look as good when you viewed the hidden picture) but I am working on that, too.

Here are the first couple:

SpaceAce

Whoa! They look like shit on GFY. I think it's the grey GFY background. Try loading them into a browser by themselves, they look way cooler that way :)

SpaceAce

Yeah, they look WAY better in a browser by themselves. I'll have to take that into account in the future.

SpaceAce

save it as jpg

I didn't care for the way they came out as jpegs. The hidden images lost detail because of the lossy compression.

SpaceAce

Yeah, GIF or another no-loss format is needed, since each pixel matters. Sorry, I didn't save the PSD. Looks like you got everything right SpaceAce, just a matter of picking the right images and right contrast/brightness for the images to improve them. I think you'd do better with a higher-contrast, busier foreground image. Large same-color areas like the street in one of your pics let the image beneath show through, and I'd guess your swirl was little dim (lower contrast) to begin with.

Actually, I got the swirl by using the liquify filter on the goatse.cx ass pic :) The low-contrast look is a result of one of the checkerboards. The method I use leaves one of the checkerboards in "normal" blend mode.

SpaceAce

Here's another:

SpaceAce

Man, what is it with this grey background on GFY? In my graphics program and in a browser by itself, that thing is golden; there is no indication of the secondary picture. here on GFY, you can sort of see the bottom picture. Maybe I should just greyscale all the images.
