Somebody asked me if it is possible to make images in Photoshop where there are hidden messages you can only see when you put on the special glasses. Like those 3d paper glasses, but where both lenses are red or blue.

Has anybody done that, or seen a plug in that creates them?

Links or keywords would also be appreciated.

Thanks
Mathias

I think you need to buy the glasses to find out.

Those hidden messages are usually created by printing them in a light cyan and superimposing a very busy pattern printed in red which obscures the light cyan image, and then viewing the whole thing through a red filter, thus making the red pattern disappear, and the cyan pattern becoming very visable.

No anaglyph glasses, just red

Make your hidden message in 215R/255G/255B.

Add a layer on top set to multiply and fill it with some very busy pattern that fills the whole canvas and set it in 255R/0G/0B.

That’s pretty much it. Though if you printed it you might be better of specifying the colors in CYMK 10-15% cyan for the message, 100M/100Y for the pattern

To simulate viewing with a red filter, put a layer on top also set to multiply and fill the entire thing with 255R/0G/0B.

Turn it on and off to see your message appear and disappear.
