There is a double diagonal effect to this image – the backs of these pigs each forms an individual diagonal, and the resulting row of pigs itself flows in a single diagonal line from upper left to lower right. It was important to break this diagonal flow with just one visible head. The pigs were eating at this moment and I waited for one to stop and raise its head for just an instant. That pig is still part of the diagonal orientation, but at the same time, it also becomes distinct from it – a point of emphasis.
