But my problem is that surely its only there if it is obvious?

If you look at a plain brick wall and only see bricks, that is because your eyes are giving you the correct information.

If you look at a brick wall and see a hamster, then thats because your eyes are decieving you/trick of light and shadow/you want to see a hamster. At the end of the day, the fact is that it is a wall of bricks, not a hamster, neither does it have a multi layered hamster imprinted on it.

BUT, like I said, I have seen with my own eyes photos with such anomalies, obvious anomalies, that they can't be denied as at the very least "very odd".....such as that one with the creature sitting in a pose in the landscape.

That wasn't a so called "multi layered" photo, whatever one of those is.....that was just a photo of landscape but with a very prominent anomaly within that photo. I'd love to know what that is, be it a live creature, a statue, whatever.
