At first glance you might see a man heading into the woods, wearing a jacket with a picture of a tiger on the back. Right? It's actually a black poodle coming out of the woods.
the first one i only saw snow, forest and fuzzy dog. non of those other things described as being at first sight. i can make our something that could be interpreted as a person, but can't find the tiger save me. the second one got me though. it was simply totally unclear what i was looking at.
The dog's head would be the tiger's head on the back of a man's jacket. Or maybe a dog's head or some other animal.
Is this orangutan climbing upward or downward? He's going upward, the jungle floor is flooded and the tops of the trees and the sky are reflected in the water.
Removing the background corrects the parallax deliberate error on the original, changing the perception by around 50% The remaining 50% is in our natural perception of size vs distance We can see a cloud through our bedroom window, but our brain is trained to accept that a cloud is larger than a pane of glass. Likewise, the guy walking along the other side of the road is more than 18 inches tall You could play for hours looking up into the night sky and guessing the TRUE size of all those little stars.
