Some close- and closer-ups of the Optic Cloak:
What these photos, photoed just after I’d photoed these photos, only show a few glimpses of is how different the OC looks, depending on the light’s strength, its direction, and its colour. All of the above photos were photoed from the western, upstream side of the OC, as I moved from north to south, and all on the same day. There’s a whole different set to be taken from the east, or from the West on a different day.
This is something that all the best London Things, Big or, as in this case, not so Big, have in common. (I’m thinking in particular of the Shard and of the Walkie Talkie and, more recently, of the Scalpel (which is only very small in that photo, but which does wonderful things with the light).)
