So how does one go about camouflaging a ship during wartime?

That was the question that troubled Britain during World War 1.

Germanys U-boats were creating havoc in the Atlantic sinking merchant ships in alarming numbers.

Bold shapes at the bow and stern can make it difficult to tell apart one from the other.

The illusion is furthered by angled lines that make the smokestacks seem to be leaning in another direction.

Wilkinson developed hundreds of camouflage schemes.

The Americans also adopted dazzle patterns for camouflage, painting some 1,200 merchant vessels with Wilkinsons design.

Statistically, it is hard to say whether dazzle camouflage worked.

But camouflage on aircraft was found to be less effective.
