Little Storm at Sunset

The day had been partly cloudy with no hint of rain when out of nowhere this little storm showed up. From the house, I grabbed the 24-70 f/4 L IS, installed a CPOL filter, mounted the lens to a 5D Mark III and ran for the clearing.
 
I quickly framed and shot a wide variety of images. For this particular composition, I used the in-the-shade section of mountain as a clean base with the rest of the details creating an overall balance to the image. I shot what looked right to me, but many of the lines fall into the rule-of-thirds. The warm color is courtesy of the setting sun.
 
The f/5.6 aperture is rather wide for an all-in-focus landscape photo, but with no close subjects, this aperture provided adequate depth of field. With the no-time constraint this rainbow opportunity provided, I relied on image stabilization to capture a sharp 1/20 second image at 70mm – in the wind. I clone stamped a few blowing leaves out of the foreground of this image, but left the leaves in some of the captures with larger quantities of blowing leaves in them, better revealing the windy conditions.
