Most sports pictures dont resonate with me; however a good swimming picture often stops me in my tracks. Swimming is a difficult sport to shoot. Much of the action happens under water. Its difficult to pre-focus on where you are SURE the swimmer will pop up for a breath, AND the action happens so fast. The ambient light in many pools is pretty tough to deal with. Its often dark and flat. I like Donald Miralles approach here. The use of artificial lighting freezes the action and provides great modeling.
