Came across this article which makes interesting reading especially for those wondering about composition and focus. Interesting articles all through site I recomend the one for using a grey card too.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
