A good example of how it was supposed to work - it really is hard to figure out where the ship is actually heading: <a href="https://en.wikipedia.org/wiki/Dazzle_camouflage#/media/File:EB1922_Camouflage_Periscope_View.jpg" rel="nofollow">https://en.wikipedia.org/wiki/Dazzle_camouflage#/media/File:...</a>
I was under the impression that the effectiveness of Dazzle camouflage was debatable, if not outright ineffective? There were no standardized patterns by which they could be studied for their effectiveness in WWI, and by WWII when such schemes were standardized, they were rendered moot by rangefinders and radar.
There's a modern example of this at anchor in Edinburgh: <a href="https://edinburghartfestival.com/dazzle" rel="nofollow">https://edinburghartfestival.com/dazzle</a><p>I've seen it in person, but what I've not tried and I wonder if anyone has, is photographing it from some distance across the sea to see if it's meaningfully camouflaged. I'm not sure that's possible at it's current location because of the harbour.
