Hidden Photo Optical Illusion

To see the hidden image tilt the computer screen, look at the screen from a side angle, step away from the screen, or shake your head really fast. The image is almost completely invisible if viewing strait on and semi close.

I was looking at optical illusions when I came across "John Lennon optical illusion." See link below for the illusion.

I looked on the internet for a tutorial but couldn't find one. After playing around with Photoshop I came up with this Instructable.

Here is the finished file. 
 


This can be done with a photo or text.

Step 1: Black and White lines

Open a new Photoshop file.
Make the size 4 px wide and 9 px long (image 1.)
Zoom in if needed to see.
Use the Single Column Marquee tool  to select 1 column of px (image 2.)
Use the paint bucket tool to fill column. Follow the color scheme, black gray(9f9f9f) white gray(9f9f9f), as seen in image 3.
Define the pattern Edit / Define pattern (images 4 and 5.)


Step 2: The Hidden photo

Select a photo or text and open it in a new Photoshop tab (This works better if the photo is a close up shot.)
Use the quick selection tool to select the background of the photo and press delete to remove the background (image 2.)
Image/ adjustments/ Desatureate  to remove the color (Image 3.)

This makes my eyes hurt. I now have a headache. I have come to the conclusion that John Lennon is secretly evil.
that is seriously awesome, the instructions are not brilliantly clear though and i would like to know how to do it with GIMP.

Thank you for this tutorial .. However I had an issue .. if I saved the file as jpg or png or even dragged the file to illustrator or indesign the lines change and It is not working anymore ...how can I ensure that the image preserves itself to have the same effect in screen on different softwares and also in printing??... Thank you!

You should combine this method with the double face one. It would have people really wondering what they were seeing, but liking it.

Interesting, but not so hidden...
coaleu (author)  rimar20002 years ago
Thanks for the comment. Yeah my face really isn't that hidden. How hidden it is has to do with angle of view and size/distance from the screen. I didn't want to make it that hard to see the image. The lower the opacity the harder it is to see and makes it where you have to look at more of an extreme angle to see the hidden image. The attached image is a lot harder to see. I have to tilt my laptop screen at at 135° to see the image.
