WWI's 'Dazzle' camouflage was a creative approach to confuse enemy submarines regarding the speed and heading of ships. The technique utilized bold patterns to produce optical effects that misled enemy rangefinders, thus making it difficult for them to accurately assess targets. H.I. Sutton's video regarding this topic further explains these benefits and introduces the concept of the 'horizon effect' but lacks comprehensive academic explanations. The discussion also hints at the significance of stereoscopic rangefinders used by surface navies in relation to Dazzle's effectiveness, indicating a comprehensive understanding of naval targeting during this period could involve multiple technologies.
