Not too long ago, I was reading about master photographer and husband of Georgia O'Keefe, Alfred Stieglitz, and was fascinated to learn that he did a series of abstracted cloudscape photos, titled the Equivalent Series. How exciting to learn that one of the great photographers of the late 19th/early 20th century was also a cloud aficionado.
Whereas these shots were taken in full afternoon sun, against a brilliant blue sky, I find that I prefer them, save one, as monochromatics, just as Stieglitz portrayed them. They are posted by date taken, earliest to latest. Location, date and cloud type are noted. All, except for the color photo, are taken at full 18mm wide angle.
So, Mr. Stieglitz, wherever you may be, here's a tribute to you and your Equivalents. Enjoy!

This pair of moisture-laden cumulus congestus clouds, joined by a thin vapor veil, show dramatic backlighting from the sun.
