Solution, FAQ and sources

Solution

Use the studs around the frame to split the picture into ten equal squares.

1. Eight of the squares come in pairs, where one is the colour-reverse of the other. Each pair adds up to one square of sky and one square of cloud, so the eight give 4 sky and 4 cloud. 2. The two remaining squares are all sky.

That's **6 sky to 4 cloud**. (The squares can only be seen in the picture; two independent sources agree on the pairing and the answer.)

About this puzzle

A fellow passenger shows you a picture with a total area of 10 and asks how much of it is sky and how much is cloud. He insists there’s a definite method, not guesswork.
