These pictures are stereograms: squint at them. I have never been able reliably to diverge my eyes from their focus point, but I have been able to converge them. A ruined Sub. B class photo from 1984 attests to my skill at this. Therefore, these stereo images are made for a converging squint. Don't worry if you struggle with the Agapanthus - the view points are too far apart, so I can see only a part of the flower at a time in 3D. The rest of the flower appears like a confusing mess of blue. The Iris OTOH is a beaut!
(If anyone could effect a more specific ID of the species, I would be grateful for a comment or two.)
