GigaPan Beta + Sony DSC-H7


I discovered this little glade with its wonderful sculpture in Bath's Botanical Garden the other day.

I asked my model, Gem, to strike a few poses while I ran the robot over the scene and quite accidentally it has produced a convincing optical illusion. To my eye, the image of Gem second from the right is *way* too small compared to the image of her in the centre. Of course she is closer to the camera in the centre so the image should be bigger - but *that* much bigger?

What is going on here? Is there some well-known principle at work eg converging lines making objects of the same size look differently-sized? Is it something to do with the stitching software? (Autopano Pro in this case, but the effect is present in the GP stitcher version too.)

    Due to the visual height difference perspective of your model, this appears to be an excellent example of an optical illusion. The first of this type I have seen on gigapan.org. Everyone can now see what an optical illusion is.
