Yeah, I tried several distortions to the steg'd image. Even if you slightly change the brightness (Which WILL happen if you scan) the hidden image is destroyed.
It WAS a nice thought though.
UPDATE:
OoOoOoOoO.
I just tried this: I took an image and set the transparency ADJUSTMENT to about the first setting so it wasn't visible but technically barely opaque.
Then I put this image on top of a white canvas.
Then I ran the reveal tool and it came up. (kinda light, just use the levels tool to fix that)
This method let's the image survive twist, oblique, ANY rotation and more.
Sadly, noise still kills it. It's a start though.
Sorry if I seem kind of obsessed. I'm truly fascinated with this steganography concept
Thanks for listening
