Cloudy skies on sunny days

Clouds look different in IR – solid cloud looks fairly blah, and cloudless sky uninteresting, but skies that are sunny with vague wisps of white cloud have a hidden and dramatic turbulence.

Technically: A6000 IR mod camera with 650nm filter on 16mm lens.  F5, iso 100, 1/350 and 1/500 sec.  Slightly odd settings, but wider f-stop seemed to work better in this light, with this lens.
