I’m not actually a fan of mud. It clings to my shoes, leads to more frequent clothes washing, makes pathways impassable, occasionally causes me to slip and slide and fall over on my backside. But, when I noticed a patch of fallen leaves lying in mud, I rather liked how they looked, how the mud helped to highlight the veins. And, when I got home and looked more closely at my photographs, this one leaf looked to me like a lung. And so I manipulated the image, cropping the photo then flipping it horizontally and pasting the two parts together. Et voilà!
