Big Horn Sheep side view
This is the view I mentioned in the previous post. It is hard to see the form of the diorama shell. It curves towards the viewer quite gently on the left, where it is closer to the viewer, and sharply to the right where it is further away. The pictorial information suggests almost the opposite, so your consciousness is struggling with the assembly. There is a similar problem with the floating shadows from instrument six, which do things that shadows are not supposed to do. We believe shadows so implicitly that we try and put them back where they should be, even though we perceive them to be floating in space.
Usual process for resolving the stereoscopic image (See the post below if you are new to the blog).
