Racing the shadows
Canon 1DX MKII 24mm lens 500th/sec F4
You get huge cloud formations at COTA (the Circuit of the Americas). You can see them rolling in from the tower. That’s what created the shadow in the left-hand part of the frame. I distinctly recall this shot becoming a race within a race, for its success relied entirely on the car being in the frame before the fast-moving shadow swallowed the remaining light and killed the image.
