No special equipment is needed, or super camera to take this shot. A good pair of wellingtons or waders is more usueful so I agree with the sentiments of the article it is what the photograph is about not what equipment it's taken with. 

"You cannot depend upon your eyes if your imagination is out of focus"  - Mark Twain

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.

Edward Lear
